I recently picked up a few Pactra paints for Polycarbonate in a bulk purchase on everyone's favorite auction site. Having never used them, I'm curious as to if they can be used on styrene. I'm kinda thinking that as long as the styrene is primed, it should be ok, but don't want to waste a good kit to ruined body. Does anyone have experience in using these paints? Any tips or things to avoid? BTW, these are in rattle cans, if that makes any difference.
