these hair line cracks are pissin me off!, how do i get rid of them? i googled and people were saying to make the crack worse so you could actually fill it, but that won't work in my case since there is like 20 cracks in 1 tiny area, i don't want to sand past the top gel into fiberglass, cuz i know i'm going to get deep dips and not fill it in right, its in an awkward spot on my rear bumper..

what if i just used 2k build primer on it, sanded it, then shot it again with like 3 coats of 2k, would that work?

heres a pic of the fun stuff..

resin!!
