Hey everyone, I have some large panels of polystyrene I want to paint black on one side and white on the other. This is something a film maker might use to control light spill or bounce back light. However I am unsure which kind of paint to use, could you please advise? A friend of mine also did this but whenever someone touches the black side of his panel they get black stains on their hands, I don't want this to happen to mine.(By the way, spray painting is not an option, as I am painting inside a indoor home small space)Thank you! via /r/DIY https://ift.tt/2q2gHxK
