So recently I purchased some resin cast parts. I usually spray these with a flat black primer that is formulated for plastic. However this time, I got some unexpected results. I sprayed them as I normally do and everything looked fine. Then I walked away for a few minutes. When I came back, the paint had beaded up and looked like crap. The guy who made the parts said he doesn't use any teflon spray or anything in his parts, so he's not quite sure what happened. Is it possible that whatever his resin is, it's different from other people's so much that it reacts differently to paint?
The paint I used is Krylon Flat Black Primer for plastic.
Also, does anyone have any suggestions for getting the beaded paint off? I figured I'd have to sand them because anything that could remove the paint was going to melt the resin.
Thanks!
