I refinish every used bow I get. Hardly any work at all. Like many have suggested. Lightly sand the bow and get all the wax you put on, off. You don't have the get to the wood. Get all the wax off and spray with an outdoor Poly, give it a light coat and sand with 00 stell wool then give it another coat and you are good to go
( Just a side note, next time you have a problem with a bow don't go on a website complainig there is a problem with a bow when you don't know what you are talking about, you didn't have to say what kind of bow it was. Do you think they appreciate you basically saying to the world they have a crappy finish)
