From what I've read, about a 120 grit sandpaper is best for sanding plastic before painting, but after testing it seems to be a bit too corse and am worried that the scratch marks left by this grit could show after painting. On the other hand, if sanded with a sandpaper grit that is too high, will that mean that paint might not stick very well to the surface? Thanks. via /r/DIY https://ift.tt/33hO5C8
