fixing to paint my '80 chevy, truck has 53000 actual miles from new, 0 rust, i small scrape from a farm gate [ at 6 mpg we don't use it much, since about '89] paint is factory, now the factory paint is the old light metallic blue, this did not have much 'shine' when new, i plan to do another factory paint to the truck,single stage to keep it original looking , im thinking about using clearcoat to make the truck blue have some depth, but to me nothing looks worse than all these modern cars with flaking clearcoat on them once they get to be a few years old, is clearcoat feasible on single stage, and how many coats should i apply to make the stuff last awhile?
