Can't say I agree with you Steve.. I used to have a white hull and used bbs after every trip but unless I gave the boat a good coat of carnauba wax once or twice a year I would get scum lines. BBS is a great product but I highly doubt it would replace a good coat of wax. Think about it.. It's a liquid spray, what % of it is wax? It can't be a high % because when you spray it on plastic it's not a pain in the a$$ to remove like a true wax is. Still one of the best products I've used!! and I've used quite a few lol
