That 'LokTite Marine PL' adhesive/sealant says it is paintable. On paper it looks to be as good as LifeCaulk or 5200 but says it is a 'polyether' base sealant whereas the other 2 are 'polyurethane' base. A chemist I'm not ... even if I slept at the Holiday Inn last night.... I just had never heard of it and have no experience with it, but again - it looks good on paper. I have a friend who's a Sales Rep for LokTite, I'll ask him for a comparison to LifeCaulk and 5200. Just be sure to etch and prime any area, even if just vinegar washed, before applying the goop, as some sealants do attach bare tin.
