That's the warning I've encountered regarding 5200--it's great when you really want something permanently bonded, but not for sealing a fitting that will need to be removed in the future. Our local sailing shop guru says that 5200 should be considered a cement rather than a sealer. Anyway, that's why I'm going to do the silicone instead. Unfortunately, very damp conditions today will keep my from doing anything until tomorrow. <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />
