I have a 1968 Shakespeare Necaduh bow. It has a residue on the outside of the limbs, where someone has put some kind tape, etc. on it then tried to pull it off. The poly finish on the wood part of of the bow is showing a lot of cracking. Can anyone give me some guidance on any books, videos, refinishing kits, personal knowledge, etc, to help me refinish this bow? Never done this before. Maybe use a little acetone to clean the residue off then sand and refinish the wood part. The glass backing on it has some scratches on it. Can these be buffed out? Any help will be greatly appreciated.
