i`ve painted three skis with car paint with no problem, been painting cars for years. use base clear and dont put it to heavy, thats what people do wrong is make it to thick then it will shink and crack. makes also makes it brittle too so if you have a flexing spot it will come right off, chip easy. so base color just enough so you dont see though it and clear one dust coat and one shine coat. thats how all your new cars are painted
