I was with him when it was happening..basically the finish was absorbing moisture and getting all cloudy all over the bow. Being a 2002 I bet it was some kinda polyurethane and not a current quality level hardened epoxy. I'm thinking either he needs to do like Ron said and let it dry out, do a partial refinish at home and just keep it heavily waxed, or worst case maybe a professional refinish with something up to date to really insure against any future issues. Was great hunting with you bro! Rain or not fortune favors the bold!!
