I hate to be a "fly in this ointment" but if I spend 200 hours filling and blocksanding(like I just did) I am not going to roll on the paint and I have NEVER seen anything but epoxy or etch primer stick effectively to bare metal. If this stuff is Canada's version of Rustoleum it will not stick sufficiently enough to bare metal for me to paint a "cool" car with. Maybe a "winter beater" -Bob
