Alkyld enamels, such as Rustoluem, two biggest faults are chalking due to UV light exposure (from the sun, etc.) and chemical resistance. Adding some hardener will increase the chemical resistance considerably. Parts underneath the car receive minimal UV light exposure, so Rustoleum with some hardener added should hold up well. This type of finish would be acceptable for a summer time week-end car.



Will any kind of hardener for enamel work?
