+ 1 on the Krylon BBQ. I have tried several "Rustoleum" products, they usually got gummy or wiped under oil.
One finish I did though with Rustoleum that came out sort of neat was thier "black" hammered finish. It actually isnt black, it is more charcoal grey and closely resembles the finish on the PSO-1 scopes, very close.
I too would like to know what is the best coating I could lay down on a blaster without going the Dura coat, Alumahyde, gun kote route.
I am a cheap a$$ and also would like to pick it up locally as opposed to mail order.
