Is that the T track that I sent you? What problems did you have with the paint? Did you use a primer before you painted? I haven't had any paint issues thus far, and Ive used it on 3 blasters. I use the Colorplace blue label rattlecan primer before I paint. So far Ive paired that up with Krylon Fusion Satin black, ColorPlace whitelabel Flat black and ColorPlace blue label flat black.
Its hard to tell from the pictures but it looks like your paint wrinkled on the T track, is that what happened?
