I used John Deere Blitz black when I sprayed my truck. I am a guy who likes the hot rod primer look and this paint was nine bucks a quart. It has a semi gloss look to it and will not absorb moisture like primer will. It cost me less money to spray it than rattle cans and offers me some protection from the elements. I tried the JD thinner but it actually flowed better with nothing at all. For thirty bucks I'm satisfied..............Dale
