Brownells sells the stuff as do other suppliers, and a lot of people offer this service for varied fees. Now hard hard can this stuff be to use yourself at home? I guess the hardest part is finding a big enough oven? Or is there more to curing this stuff than I think?

Edblevi,
The stuff Brownells sells isn't too hard to use.  I refinished a 1911 with one of their spray cans.  As many people have said here before, the spray cans are a little heavy on the spray.  An airbrush would give a finer and more easily controlled spray, but the cans do work.

As for actually using the stuff just follow the directions on the can.  Bead/sand blast, clean with degreaser, heat parts, spray and back.  DO NOT try spraying this stuff indoors, unless you already have a paint booth setup.  Once the parts have been sprayed the smell and fumes aren't bad.  And you can get away with using the kitchen oven if your parts will fit.  I did this one night when the wife was gone.  The next day she had no idea.

I don't believe the durability of the do it yourself sprays is anywhere near that of the professional sprays.  After about 10 presentations from a holster the finish was rubbing off on my handgun.  However, for $25 it works for me, until I can have it redone by a pro.

Hope this helps.
Scott

Its not hard.

The problem is that paint on firearms is chessy, with the possible exception of a POS AK.
