Rearview mirror glue
I want to glue a piece of steel to my truck's windshield, with some
threaded holes so I can attach anything to it (such as radar detector, parking permits etc). My question is, what sort of steel glues best and what is the right surface prep. Should I sandpaper it? Should I sandpaper the glass? What is that rearview glue exactly? Also what is the minimum ambient temp at which I can do the gluing. i |

My question is, what sort of steel glues best Clean, smooth, flat, and small (large pieces won't mate to the curvature of the windshield -- you want something the size of a rearview mirror mounting button). and what is the right surface prep. Should I sandpaper it? Should I sandpaper the glass? No to both. What is that rearview glue exactly? Cyanoacrylate aka "superglue". Also what is the minimum ambient temp at which I can do the gluing. Consult the manufacturer of the glue. Typically 60F and up, I believe. |

Yep and what is the right surface prep. Should I sandpaper it? Should I sandpaper the glass? No to both. Yep What is that rearview glue exactly? Cyanoacrylate aka "superglue". Nope. There are specific rear view mirror glues from Locktite that work very well. Also what is the minimum ambient temp at which I can do the gluing. Consult the manufacturer of the glue. Typically 60F and up, I believe. Yes, reasonably warm temps are needed. The other option would be a somewhat larger plate and some of the 3M VHB very high bond DS foam tape where the foam will help compensate for the windshield curvature. |

My question is, what sort of steel glues best and what is the right surface prep. Flat. Should I sandpaper it? Yes, it can't hurt. Should I sandpaper the glass? ABSOLUTELY NOT! What is that rearview glue exactly? Polyester Acrylic Epoxy? http://fwd4.me/rMU purchase one, http://fwd4.me/rMV msds Also what is the minimum ambient temp at which I can do the gluing. Much higher than in Illinoise in the Wintertime. RTFM, sir. Then don't even consider gluing at anywhere near the low temp. It works better at higher temps. I know this from many reglues in the warmer climes of LoCal. Nearly every wreck that came into the body shop had a blown mirror or broken windshield, so I learned how to remove the tab, clean it up, and glue it on the new w/s. http://fwd4.me/rMY 65-85F, but after curing, it's good for -130 to +230F. Since LoCal was always 70F, it wasn't a problem for me. ;) -- "Human nature itself is evermore an advocate for liberty.

Consult the manufacturer of the glue. Typically 60F and up, I believe. NO-NOT SUPERGLUE! The proper stuff can be had at the auto parts places, it's a two-part glue, vinyl-based, same as OEM. Has enough flexibility to take up the difference in temperature coefficients between glass and metal. FOLLOW DIRECTIONS! Failure to do so will result in the part ending up in your lap at the worst possible time. The stuff I've used was under the Loctite label, has lasted about 10 years so far. If you're designing something, grab a rearview mirror and mounting button off a wreck and you'll be miles ahead. Usually a couple of bucks for the non-powered kind from a U-Pullit. Put your holes in the shoe that mounts to the button, not the button itself. Another thing to check is local and state laws about stuff around the rearview mirror, some states are picky about having absolutely nothing except the mirror on the windshield. Tickets for same can be costly. Stan |

Tim Wescott fired this volley in
: IIRC the stuff that I have in my '69 Chevy was one-part, Most of them are, except that they use an "activator". It's not truly a two-part system. The activator merely kick-starts the naturally slower cure process. I has only to make contact with one side of the film to have its effect, sort of like "Zip Kicker" for CAs. But Mirror Glue isn't a CA. Last one I used was a Methacrylate, similar to some thread-lockers, but transparent. LLoyd |

I followed the instruction on the back exactly. I sanded the puck and the glass and put it back with JB Weld. It stayed. Infact when the car was junked I tried to save the mirror because the one in my truck then was cracked. I had to break the windshield and grind off the glass to get the puck. |

I followed the instruction on the back exactly. It sounds like you didn't hold it tightly against the glass for about two minutes. I've seen guys tape 'em up after pressing them on, but that doesn't work. YOu have to expend the time and energy to hold them tight and immovable against the glass for at least 120 contiguous seconds or the bond fails. DAMHIKT @ $5 a pop in '70s dollars...

I went three or four years with an annual reglue of the mirror puck (with careful sanding, cleaning with alcohol, and use of the solvent) in my old Lebaron, using the "official" cement (once bought from Chrysler, other times from NAPA). When I gave up and JB Welded it, it stayed on from then until we sold the car, probably a decade or more later. -- As we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously.
