Hey Guys, Ok so its coming time to paint my pickup. I have done small paint jobs before, but never anything so big, usually just flashes, dash / interiors and roofs. I am wanting to do a flat paint job, and digging the hot rod flatz colors. Ok so here come some dumb questions: 1. My pickup is in primer, only a light coat and has been rubbed back to metal underneath. IS there a risk that not knowing what kind of primer it is if I lay color on top it might react badly with the existing primer? (i didnt spray it so I have no idea what was used!) 2. Its an AD chevy pickup - how much hot rod flatz am I gonna need to do this right? Any other advice you can give me would be appreciated!
