Being honest, I gave on using this stuff as a clear coat a few years ago, my last few times at using it, after a few months, the entire body was covered in spiderweb cracks, so I have no idea why it kept happening , this happened on about 3 out the 5 that I used it on. I read somewhere that if the paint isnt cured that will casue it, but I busted that one, as one of them had been painted about a year before, and it was lacquer paint. So for the TL/DR, I will only use this stuff for making clear parts look better.
