I've been talking to my neighbor who works in an auto paint shop and he tells me there are ceramic clear coat that are very scratch resistant.I'm thinking about having my red Jeep touched up and clear coated
If you want a true clear coat out of a rattle can you need to look into "Spray Max 2k Urethane Glamour Coat" it's more pricey but I promise you will get much better results than any other brand. I do a lot of touch ups, fiberglass work and etc on the side and nothing has come close to that. Of course when I spray from a gun, it comes out a little smoother right off the bat but nothing a little Polish wouldn't smooth out. I will try to find a picture of some wheels I did a couple months ago
Rattle type of regular gun?
If it's the regular gun the amount of hardener has a big impact. The harder it is the more it will resist scratching, but the less it will deflect before chipping.
If rattle can the hardener ratio is set. I have used Rustoleum "Crystal Clear" but have has some troubles with it. If the paint is not COMPLETELY set up the thinners in the clear will cause wrinkling in the base color. This sucks as the only fix is to sand it off and start over. It does work well though on things like Bilstein shocks. (Spray them when new to help with oxidation.)
I assume this is prep for the cage?
Speaking of clearing the bilstein shocks, did it help the finish last longer? I don't want mine to look terrible after only having them a few months
It does help some, but honestly the best thing I've found is to regularly wipe them off with silicone based WD-40.
