Andrei, If I were going to store my boat in the water and wanted good protection from blisters I would apply 5 to 7 coats of Interlux 2000/2001 barrier coat with the applications EXACTLY as directions (notably -tack time, and mixing components). I have heard anecdotally, that cool fresh water is less prone to causing blisters - but do you want to be a part of the ongoing test? Probably not. Barrier coat and dry bilges are the best defense against blistering in your case. FWIW -I base my opinion on 30 years of maintaining late 60's thru late 90's built polyester resin sailboats in warm freshwater as a former marina operator. If you put the boat in the water, use barrier coat for your best protection for what you have, anti-fouling is optional. IMHO worth all of what was charged. Just another to add to your confusion - sorry. Take Care, Have Fun, Go Sailing! GO M-17 # 316a LB/GF! In a message dated 10/17/2008 7:13:21 A.M.

Thanks, Andrei. _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats **************New MapQuest Local shows what's happening at your destination.
