I am 99% sure I want to try this and you are th efirst to mention a hardening agent. How would you use that with a roller? anything to watch out for? I am tempted to try a tailgats, since that needs the paint the worst anyway,
One ohter question, my paint is relatively good already, hate the color, bbut there is some cracking,would simple sanding and feathering be enough or do I need to take it down to bare metal and then prime??
