I know it says it "bonds with the plastic" but here's what happened to me today. I sprayed green on a fender about a week and a half ago. I realized today that I missed a spot, and my green for handpainting is a shade off, so I sprayed it again. these lines started forming in the paint, and then it spread like a spiderweb. I then proceeded to wipe all the paint off with a paper towel. I think I had previously put down about 4 coats. any ideas?
