As a devoted lurker and sometimes smurker :-), I am reluctant to bring to this esteemed list such a mundane request for ideas on how best to waterproof a Sunbrella fly bridge enclosure. I would prefer to leave it in the deployed state if possible but it would be difficult to reach all top areas, 12x14, with a brush or roller and over spray will be a problem. Is there anything that has been applied from the inside that worked? Any creative technique helpful. Thanks in advance for the insights. Jim Grace "Aglaia" 43' Tradewinds
