I recently tried a project with Brownell's Baking Laquer. I did a lot of research on the net first, then gave it a shot. IT SUCKS! DO NOT USE IT! It looks tuff at first, but it scratches and flakes pretty easily.
It costs about $11 per can, but shipping is another $8 if that's all you order. The ad says just prep and spray any metal surface. But the back of the can says best if used on bead blasted or parkerized surface.
The rifle was a 98/22 Czech Mauser in 8mm. I sanded all surfaces with 300 grit paper, then warmed everything in the oven to bake out any oil. Then I sanded to 400 grit followed by 00 steel wool. I degreased with brake cleaner, then acetone. Twice, very thouroghly. Wore gloves.
Warmed the small parts first, then sprayed 3 coats of flat black. I was having some problems with fish-eyes from silicone maybe? I had to put 4-5 coats on some larger areas because of this. Baked according to directions. Let it cool while I did the barreled action the same way.
The finish looks awesome! But it scratches pretty easily. Once there is a scratch, the rest flakes very easily. Just lightly dragging an empty shell over the finish is enough to ruin it. There's no way this stuff will hold up for a few years without looking crappy. Also, some metal parts held the finish pretty well, while other parts made of different metal easily flaked with fingernail pressure. Like the rear sight and ramp for example.
I stripped it off with commercial paint stripper. I would never use Brownell's Baking Laquer on a gun. Perhaps a parkerized finish will hold it better without flaking, but don't use it on a regular blued gun. But why ruin a nice parkerized job? Rustolium would probably be a better choice over this stuff. :evil:
