May have a lot of trouble with metalics or candy colors though. A scanner uses CCFL tubes which are not the best choice for color rendition. A good automotive paint store can use a color corrected system to match the paint, or you can take your chances by using the Vehicle's OEM paint number. -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge. |

Bring in something you want matched, they scan it, and the system automatically dispenses the various paints into the proper color and shade. Its actually pretty damned accurate, based on some of the machines Ive repainted recently Gunner -- "First Law of Leftist Debate The more you present a leftist with factual evidence that is counter to his preconceived world view and the more difficult it becomes for him to refute it without losing face the chance of him calling you a racist, bigot, homophobe approaches infinity.

Basically a spectrometer hooked to a computer, tells how much of what to squirt into the base. Or they can look up the OEM paint number on the build sticker and go from that in the built-in database. Downside to that is that you'll get the factory-new color, not what it's been faded out to right now. One reason to redo whole panels instead of just spots, unless you like the "leopard" look. And it's really hard to spot-fix clear-coat jobs. Can be done, but takes a LOT of skill. Spray can paint will last, at most, a couple of years on a car before it fades, chalks or peels. Not worth doing for a really big spot. It just doesn't have what it takes to survive automotive use. DAMHIK Stan |

I got a chance to do a little playing this weekend. A trip to the auto supply turned up a Dupli-Color spray can in Oxford white for something to play with. I took my Porter Cable random orbit sander with 220 grit paper(the finest I could find for it) and sanded down some areas that needed touched up. The sand paper was quite aggressive right at first but after a little wear it seemed OK. After sanding and feathering I wet sanded with 320, then dried and cleaned everything. I shot some self etching primer on the areas that got to bare metal. Cleaned off everything with wax remover and sprayed a few coats of paint. After drying there was a dry area around the area I sprayed, I wet sanded that area with 1500 until it felt smooth. Then I used rubbing compound with a wool bonnet on a DeWalt 849 polisher/buffer and polished it all smooth and glossy. It's difficult to tell what is new paint and what is old paint as far as transition but the area with new paint has no chips or other imperfections. I guess the bottom line would be that it would be better to fix it all and spray it all, just like JR said. But I was wanting to learn about blending in an area by sanding and polishing and it seemed to work well enough. That would be useful for a chip or scratch in a vehicle that doesn't need a paint job. My truck that I'm practicing on is a 92 F-350 Diesel that started as an FS truck and was then used in a landscape business, so it's scratched and dinged all over, except the couple of places I touched it up :-) The truck seems to have been kept up mechanically and drive train but the body has been somewhat neglected. I'm wanting to get a little bondo practice with it, a little more touch up, and then I'll start trying to sell it. Then I may attempt to touch up scratches in my Ranger, it has metallic paint and clear coat and I'm sure will be somewhat more difficult to make a touch up look right.

Well, working with reinforced materials requires a combination of technical knowledge and a LOT of hands-on experience. The latter is more important than the former, so a hobbyist who does a lot of it ought to make out well in the end. I love working with it, but part of the satisfaction comes from dealing with its contrariness. The reason I don't do more is that, so far, I've avoided becoming sensitized to epoxy, and I want to keep it that way; and the styrene and other nasties in polyester can make me wheeze after a full day of working inside of a boat hull. It presents some health hazards when you work with large quantities. And then, there is the fact that the day I started working for Ranger (then owned by Bangor-Punta), a 50-something guy in the shop next door, where they made Luhrs boats, died from silicosis, after 20 years of working in an atmosphere of ground fiberglass dust. -- Ed Huntress |

Auto Body metal working
I started playing with the Geo Prizm/Toyota Corolla that my wife crashed
early this year. I got the body straight enough I can at least get the fuel cap open now, and I got the rear wheel somewhat aligned, she had the control arm bent into a nice arch. If I can get the bumper back together and the tail/turn lights replaced then the car should be once again ready to drive on the road. I find all the reinfocement parts for the front bumper but I need the rear bumper. Should I put a pipe bumper on the car and cover it with the bumper cover? I'm getting frustrated finding every part I don't need and no parts I do need, it seems they only expect you to damage the front bumper. This crash involved my wife swerving while a truck coming the other way hit her rear bumper, smashing the rear quarter panel and ripping off the bumper & tail lights. Should I look for rear bumper parts from a dealer, junk yard, or fabricate my own from steel? I can spend the $150 for a new rear bumper cover but internet searches haven't show any rear bumper parts other than the plasitc cover. RogerN |

RogerN HMM, I just pulled up about 75 rear bumpers with covers within 100 miles of my shop in NY. Which year do you need? 94-97 are interchangeable. Color? How about state and close zip. I can punch it into Mitchell and see what shows for that area. OR try Car-Part.com Enter the year make and model, then for the part you want to search for Bumper Assy (Rear) includes cover. -- Steve W. |

Right now I'm pricing to see if it's worth fixing but I did get it drivable but not legal without the bumper and tail lights. I found people wanting to buy it for $175 for scrap but I can take it to the recycler myself. Just seem a shame to waste a good car over a bumper, rear quarter panel, and tail lights. I've been bending the smashed quarter panel back into shape with a 4-ton hydraulic porta power type body straightened. I have the metal functionally in place, might need some tweaks to hold the tail light correctly. Thanks RogerN |

Thanks, I saw Nance's is about 50 miles away and also lists quarter panel and tail lights for my car. If I can make one trip and get everything I need for the car it would be great. It's not that important to me that the car be cosmetically good as it is mechanically sound an reliable. I dedicate a car for work and it gets the miles and dirt, so this one with a banged up body would make a perfect work car and is in better condition and runs better than my Honda Civic. RogerN |

RogerN I can get the 3D to work but then have to fight with my eyes to get them to focus normally again... I have done a couple of low dollar paint jobs in the past. Used a short nap roller and thinned DuPont enamel automotive paint. If you thin it correctly and apply it in thin coats while sanding between coats it works. The prep work is still the critical step. Once the body is prepped you can apply the color in just about any way you like. Spraying is used primarily for three reasons, it's MUCH easier and faster than rolling and sanding each coat, you can apply thicker color with a gun so you cover in one or two coats, with metallics and clears the way the paint is laid down has a HUGE impact on what the final job looks like. With a metallic applied with roller I would bet you get an interesting finish because the flakes would likely be in small groups. Clears wouldn't work because anything that comes off the roller will show in the clear and the sanding/buffing process can destroy a clear coat. -- Steve W. (\___/) (='.'=) (")_(") |

RogerN Nobody seems to have noticed how many times he sanded the entire car! That job took at least a man-week. True, BUT that isn't bad if you figure that your saving a LOT of money and can DIY. Ever heard of the old car show staple the "20 coats of hand rubbed lacquer" paint job. You do a TON of sanding on those as well. Shoot on a thin coat, block out the car, another coat, sand. Repeat these steps until you get a perfectly flat final paint coat. Then buff the vehicle and enjoy the finish. All of these new BC/CC paints make painting FAR faster and easier than it was in the past. Still need a well prepped base but even that has changed a LOT. Used to be that you worked the metal, filed and sanded it smooth with leading at the seams. Then wiped it down with solvent and shot on your primer. Then blocked the primer and touched up any minor spots with spot putty. Then put on another coat of primer, blocked that and then started your color coats. Now you beat the dents out until they are 1/8" or so, slather on a coat of bondo, board and block the vehicle and then spray on some high build primer. Once over with a D/A and base coat it. As long as the base is even and full coverage you then just clean up any bugs/runs or crap. Then clear coat it. Bake it and your done. -- Steve W. (\___/) (='.'=) (")_(") |

Years ago (~30) I built a plastic model F-16 and used a slow drying thinner with Testors enamel, don't remember if it was turpentine or mineral spirits, anyway the paint flowed out smooth before drying and it was the slickest looking paint I ever seen on a plastic model. I like how the guy breaks all the rules, cheap paint, rolls on, cheap thinner, and get results equal or better than most do with spray. Of course you have to consider that Rustoleum doesn't have the color availability of the automotive paints, but it would be fun to try a metallic thinned with mineral spirits and applied with rollers. No overspray, minimal need to mask, doesn't need ~10+ CFM compressor to paint, if a respirator was still required it seems the filters would last much longer. RogerN Nobody seems to have noticed how many times he sanded the entire car! That job took at least a man-week. True, BUT that isn't bad if you figure that your saving a LOT of money and can DIY. Ever heard of the old car show staple the "20 coats of hand rubbed lacquer" paint job. You do a TON of sanding on those as well. Shoot on a thin coat, block out the car, another coat, sand. Repeat these steps until you get a perfectly flat final paint coat. Then buff the vehicle and enjoy the finish. All of these new BC/CC paints make painting FAR faster and easier than it was in the past. Still need a well prepped base but even that has changed a LOT. Used to be that you worked the metal, filed and sanded it smooth with leading at the seams. Then wiped it down with solvent and shot on your primer. Then blocked the primer and touched up any minor spots with spot putty. Then put on another coat of primer, blocked that and then started your color coats. Now you beat the dents out until they are 1/8" or so, slather on a coat of bondo, board and block the vehicle and then spray on some high build primer. Once over with a D/A and base coat it. As long as the base is even and full coverage you then just clean up any bugs/runs or crap. Then clear coat it. Bake it and your done. -- Steve W. (\___/) (='.'=) (")_(") On the once over with the D/A sander, do they make D/A sanders for wet sanding? What grit do you sand with, 320, 400? RogerN |

Grit depends on what coat your on. Going over a dry vehicle to break the gloss on the paint and provide tooth for a sealer - 220 Going over the final primer coat as prep for the color coat - 400 then a follow up wiping with wax and grease remover. Final sanding before a buffing - 1200 ON A HAND BLOCK! BUT you will want to practice with the D/A before you use it a lot. There are a lot of paint jobs that look like an ocean due to rocking the D/A while using it. You want to hold it FLAT on most surfaces use the edge in grooves and such. Keep in mind that after every use you will want to wipe down with W?G remover. This is due to the air supply having oil in it. I also HIGHLY recommend that if your doing ANY painting with a gun that you get a GOOD water separator and a different hose to feed the gun. Mark it and cap it off after each use. That way you have a clean air line to use. NEVER use it for tools, just gun use. -- Steve W. |

Because they put on more paint in one pass you have to be more carefull about runs,drips and orange peel from heavy paint. Once your used to them they are great. I have a descent old school gun I got from a mechanics yard sale, plus I have a Badger detail touch up gun and an air brush (150IL), pretty good stuff in its day.

I don't have any bondo goodies either, I guess I need a cheese grater type bondo file and an inline sander. For the grater I suggest the original sureform tools. Get a flat and half round profile and maybe a rat tail one if you have any holes to work around. Inline sanders vary in quality a LOT, but for most use the lower end ones work OK. Buy GOOD paper though. The cheap stuff is just that. It's kind of fun having old autos that I can learn on and not be afraid to mess up. I've gotten the quarter panel from flattened out to having a shape that resembles the shape of the original body, but it isn't pretty. RogerN Yeah there is no substitute for actual hands on when it comes to body work. I started learning as a kid of about 7 from some old school body knockers. -- Steve W. (\___/) (='.'=) (")_(") |

RogerN I painted an El Camino with a roller about 5 years ago. Black truck bed liner. It started as an innocent enough afternoon project, paint the bed with bed liner. By the end of the weekend, I'd painted the entire car with it. Extreme rat rod is what I call it. You can wash it with gasoline, it doesn't care. It laughs at shopping cart dings. The stuff is indestructible, requires no cleaning, and screams "better move, the owner of this vehicle really doesn't care." Newb |

Auto Body metal working
Currently I'm in Evansville Indiana, the company I work for sent me for
Siemens S7 PLC training. Anyway, on the way back from supper we saw a Harbor Freight store, I had never been in one before. We made it to the store at 7:40PM and they close at 8:00PM so I didn't buy anything yet, but will be going back a time or two before we leave Friday. My experience with cheap tools is that some are fine, some are crap, but I've been satisfied with most. If I use a tool enough that a cheap tool doesn't hold up then I'll get a better quality. Any recommended Harbor Freight tools to get or avoid for auto body (or other) metal working, sanding, and painting? I thought there might be some favorite HF tool recommendations to get while I'm here. Thanks! RogerN |

A year ago I bought a couple of 24" vernier calipers at HF for $7 each; closeout items, so might not be available anymore, but worth looking for. They're not super-duper items for metalworking, but great for carpentry; aluminum rather than steel, and 1/128" resolution on the inch scale, 0.05mm on the metric scale, good feel to the slide and overall good appearance. Also see if 6" digital calipers are on sale - they usually are priced about $20 at HF, but often go on sale for $15 or so, and sometimes $10. -- jiw |

Roger, based on my experience, do not buy anything at Harbor Freight
needing sharp edges or with motors. If you stick to this rule, many other things that they have will most likely work. i |

I bought one of those too. It looked good, and I was amazed you could buy anything like that for less than $10. I have yet to use it, but it looks good hanging on the pegboard. Might have to buy another for the house |

The one complete failure item from HF, about 20 years ago was a set of
flare wrenches, Pittsburgh brand. Might have improved, since then. Other than that, I've been satisfied with thier quality to price ratio. -- Christopher A.

Thanks! RogerN Have a set of their dolly-shaped cast iron lumps. They will work, if you polish them(spare the turd jokes). Same with the body hammer sets. For once or twice use, they're great, compared with what the body-supply joints get for their cast iron lumps. Sanding blocks are sanding blocks. I use the hell out of my micro die grinders, usually $10-15 on sale. Ditto the 4 1/2" angle grinders, sound terrible, but stand up to a lot of abuse. Get the ones with the metal gearbox. Test before leaving town. The Russian grinding disks for same aren't too bad. The local store also has De Walt disks, usually outlast the imports by 2-3x. The chink sandpaper is usually junk. They've had some Finnish stuff that's been pretty good. The DA sanders are decent enough when on sale, will suck your tank dry in a hurry, though. Not the most efficient pneumatic tools around. PSA sanding discs need to be bought elsewhere. Last ones I got were yellow and Finnish, got from the local discount tool joint. The HVLP conversion guns can be a good buy, if on sale, get the stand(s) if you get them. They also have spare strainers, a cleaning kit, spare parts kit, extra large aluminum cups, might be the time to get them if you buy into that. Teflon tape is always a good deal. Ditto quick-connects. They've got a three-in-one female fitting that takes all of the most common quick-connect types, might be of some use. The small touch-up/panel gun is usually pretty cheap and nice to have a couple kicking around. Same with whip hoses and swivel fittings. Have a swivel with a throttle valve built-in, that's been of some use. I have several whip hoses, reserve one exclusively for painting use, same with regular air hose. Keep the oil out of the paint guns. Their Goodyear rubber air hose is a good deal on sale. Buy quick-connects at the same time. I get the steel Ampros that are in bulk bins, not the chink brass jobbies in the bubble packs. The digital calipers have been on sale lately, the 6" usually is $10-15. Not the ones in the bubble packs, though, the ones in the real boxes are what you want. I usually have a 4" in my pocket when hitting the hardware store. They have also had a triple-threat caliper, metric/English/fractional. At one time they had a paint thickness gauge, the real electronic deal reading in microns, ran like $80 list. I picked that one up on sale for $50. They occasionally will come up with some off the wall stuff, you need to pay attention to what's on the hooks. Were selling technical drafting pens for $2 labeled as precision oilers. I've used their trailer "docking" aids, basically a pair of yellow balls on telescoping radio antennas attached to bar magnets. Amazing how easy it makes hooking up a trailer. A lot depends on whether you've got the back of a truck that you can fill or are stuck with what you can fit into your luggage if going by air. Local stores don't all carry the same stuff, either.

Any recommendations on where to buy paints? In town we have an O'Reily's,
Autozone, and Auto Pro, but I'm not sure if any of them sell paint. We used to have a Lincoln Auto Supply that sold DuPont stuff but they closed years back. Or is there a favorite place to order paints online? RogerN |
