I kmow you guys might not be able to answer but its worth a shot. I blasted, etched, alodined, zinc chromated primes and painted my outdrive with west marine anti foul paint. Ok now for $44 a spray can i am not real happy with it. Seems to be not really durable and it says black but its a flat gray. My question is and i do not keep it in the wayer but think i can paint over that paimt with gloss black rustolem really to just pretty it up?
