I am going to restore a 1960s Raleigh Superbe. The decals are original and in decent (although not perfect) condition. There is some peeling and a few scratches to them. In the past, when I restored an old frame, I simply cleaned and waxed it. However, I did not really care whether the decals remained or not (they weren't in good shape to begin with). On this bike, however, I don't want the decals to get any worse. Will waxing the frame be enough to protect them or should I do something else, such as clearcoat the frame? If the latter, any suggestions or advice on how to to do it? I've never clearcoated anything before. Thanks.
