I think i'm going to remove/sand/paint them on Saturday. Any suggestion on a paint remover than won't eat the plastic?
Yeah, i love Neon Genesis Evangelion one my favorite anime along with Rurouni Kenshin
Media Blaster would work. Sand, soda, walnuts, glass beads, etc... If the paint is only coming up in certain areas then make sure the surrounding areas are either removed or are firmly sealed. You can paint over the existing paint if it's not too thick and adhering well. I'm not sure if I'd use a chemical remover in fear od having it melt or soften the plastic.
btw: I have an extensive library of Anime.
