Thanks for the responses. As mentioned previously, I''m a newbie in this area. To the best of my recollection, the mfg.of my boat put a coat of Interlux barrier on her at time of purchase. The boat has been in fresh water for the last 6 years with only that. When I pulled her out recently, I powered washed the hull to remove all the slime,etc.Not surprisingly, a good portion of the Interlux came off as well. I''m assuming that I should have the rest removed (sanded) then have a new coat of the barrier put on, and then some type of finish over that. Is that correct? P.S.--Jeff -- I envy you being in the Annapolis area. I''ve attended several of the sailboat shows there in Oct.,and once trailered my boat up from NC to sail around the bay a bit. Back then there was a place called "Marmaduke''s" I believe, where all the sailing types hung out.It was a great place to swap tales and learn.Someone told me it''s gone now though. Anyway, Annapolis is one mighty fine sailing area!!
