Hello,
I have many things to seal. I wanted to both question, and verify, which sealant goes where.
1. Teak rub rail to fiberglass deck. This is polysulfide, such as Sikaflex or 3m 101, yes ?
2. Metal chock (is that how it is spelled) to wood - the wood is above the fiberglass, the metal chock sits on the wood so its above the rub rail, and is bolted through both wood & fiberglass. Is this polysulfide as well ?
3. Plastic to fiberglass. The stern light will be attached to the stern. It needs a wee bit of adhesive strength, as the mounting hardware for the Aqua Series 32 stern light is fairly wimpy. 3m 4200 yes?
4. Metal bolt to nylon antenna mount that is 5200'd to the fiberglass. Well I have a big 8' VHF antenna off the stern of one of my hulls, and the antenna mount was broken during shipping. Undid the bolts, and went to remove the mount. Surprise! it's attached with 5200. Joy. I found an identical mount, and was going to use a good piece off that to fix the glued-on mount, rather than try to get the thing off (whacking with a hammer did nothing, absolutely nothing). What sealant should I use when putting the bolts back? Not that they are necessary for anything more than cosmetics, nothing will ever get that stupid antenna bracket off now...
5. Plastic cable gland to fiberglass hull. I plan to scrape out whatever sealant was used to halfway-seal the VHF antenna cable to the half-inch hole it came out of, and use a proper cable gland. What sealant would I use here?
Almost done with the electrical now, not much after that, so hopefully I get this boat into the water weekend after next.
