Is it possible to spray polycarbonate paint on the outside of a hard body that flexes or will it give a dull/matte finish? Perhaps the reason the paint cracked was more to do with adhesion to the surface of the hard body. I did prepare the surface and use an undercoat but I could have sprayed it on too thick. With hindsight it was a bad idea to strip an original Holiday Buggy body and repaint it but too late now! In my defence it was a long time ago...
