I use rustoleum's hammered paints in rattle cans for just about everything and love the finish and durability. Well you're in luck, because here they come. I painted my car with rustoleum, and i think it came out amazing.
I think the por15 comes in quarts and it can be brushed or sprayed.
It gives a pretty sweet i like it because i can get it in rattle cans or quarts from lowes. Those decals on the side is actually paint. Its all in the prep. The attached photos you see is my $30.00 paint job ( 2 quarts of rustoleum, 1 quart of acetone and a small bottle of valspar enamal hardener) and was only shooting some color to be a little different than the ol' flat black we see so much of.
