work or yard truck, or something u drive every day?
if its somethign u wanna just throw paint on id do the rustoleum, if ur going to keep it a while etc use the summit paint
the black camaro nexto my name that says last picture is a camarop that was painted with black rustoleum. no prep work at all they just slapped it on there with no wetsanding or polishing and it came out pretty good.
they didnt bother with the extra work to make it look real good cause the car is being built for the 24 hours of lemons races
