Default Sources for Shellac and supplies Needed

I ordered some from http://www.shellac.net/ about a year and a half

useful to the beginner. I'm not personally familiar with using
shellac over paint or spraying, but I do have a few pieces of advice
from my experience:


Brett

Thanks for the review for shellac.net. That was one of the suppliers I
found before posting. Another response also mentioned shellac.net but
didn't say they actually bought there so I wasn't sure if it was an ad
or an endorsement.


1) I simply used the big can o' denatured alchohol from Home Depot to
mix with. Some people theorize that has too much water in it, but I
had no problems with it in a 1 pound cut. You may want to go even
thinner than that for spray finishing (I have no idea since, as I
said, I have no experience with spray finishing).


I'll try it once. I found some pretty good info on spraying shellac
so I should be ready to try why the airbrush gets here.

2) Rather than doing clear shellac over paint, why not do something
more durable? If this isn't a kid's toy (where you'd want the
edibility of shellac), you're not getting color from the blonde
shellac, so why not something harder like polyurethane?


It's a kids toy.

3) On the natural, I've had a lot of luck using shellac as an
undercoat. I use the shellac to "pop" the grain and seal the wood,
then put thin coats of polyurethane on top to provide good protection
from water (which shellac doesn't provide). I used a modified version
of the "Perfect Finish" described at
http://www.io.com/~richardr/writing/APerfectFinish/ in a couple of
projects and was pleased with the results.

4) As I understand it, the only time you need to worry about dewaxed
shellac is if you're going to use it as an undercoat and put another
finish on top. The other finish won't stick well to shellac with wax
in it. If you're going to use shellac as the final coat, don't worry
about whether it has wax or not.


shellac.net sells mostly dewaxed from what I've read so far. I'll look
at prices and it waxed is that much less maybe I'll go with the cost
savings.


My Woodcraft has both shellac and denatured alchohol. The DA is
considered a hazardous material if it's shipped more than a quart at a
time, which is why you see those weird shipping charges, can't get it
overnight (not allowed on airplanes), etc. I'd just purchase that
locally. If 95% anhydrous isn't good enough for you, just put
together a still in your shop and distill it down.


Yep I didn't realize it was considered a hazmat. That would be expensive
shipping for sure.
