I've started working with foam recently and when it came time for painting, I did something wrong. I don't know if I used too many coats or maybe it was the silver base coat I used, but the paint is cracking. I stopped putting the silver layer on the other parts and the paint doesn't Crack anymore. So my question is, is there a way to remove the paint that is cracking and repaint the parts? Or do it have to make a whole new part?
