I have just purchased an old promo that was customized and painted at some time. I'd like to strip the paint off, but not harm the old plastic. This promo dates from 1959, so I am not sure how fragile the plastic is. I've read up on the various techniques for removing paint from an injection plastic model, and from a resin model. But are there any special considerations that I need to take in mind for a quite old promo? Any help at all would be much appreciated! Thanks!
