Here's the story so far: I'm attempting to make a Con repaint of classics Mirage with a classics Rodimus's gun attached to the useless blue back piece (Rocket engine, Handle broke off, shaved down to fit, why I need the milliput)and some scrap wire I found during the store remodel (Have to figure how that's going to work. Any way, I figured the colors were fine (Black, white, Purple), But I found an interesting/Near disaterous problem. I used Krylon Fusion black to start off, figuring it would be fine to paint over. However, when I added to purple(Pactra Candy Purple), things took a very bad turn. First it didn't show on the black paint, but more alarmingly cracks and run started to show on the paint! I managed to salvage what I had done and re did the black parts (Acetone helped remove most of it, Bonds to plastic my butt!). I think I can still do the purple with games workshop handpainted (that's always available, and many shades to choose from) and the white parts are doing fine. Any ideas, or should I not tempt fate again? and am I the only one this has happened to?
