Flappn Posted June 24, 2009 Report Share Posted June 24, 2009 Hello all, I'm hoping someone can help. I have a fiberglass boat and I'm replacing what looked and feeled like the caulking where the metal bumper (the middle is rubber) meets the fiber glass, I believe it is the spot where the two halfs of the boat come together. Can some one recommend what to use to seal this? I am wondering if I should get a marine grade or just go to home depot and pick up a tube of out door clear silicon. Any help would be much appreciated. Link to comment Share on other sites More sharing options...
Fisherman Posted June 24, 2009 Report Share Posted June 24, 2009 Go with either of the 3M4200 or 3M5200. 3M4200 is a fast cure, 3M5200 takes longer to cure but both are recommended for above/below waterline in the marine environment. Should be able to get it at your local CTC. Make sure the joints are clean before starting. Silicone is best left for the bees...boobies. Link to comment Share on other sites More sharing options...
