Your sailboat’s deck hardware should have been installed using a bedding compound. (I sadly write ‘should’ as I have worked on boats where there is no evidence that bedding compound was used!) Commonly used are Sikaflex’s 291 and 3M’s 4000 and 4200 (remember, 5200 is for under the waterline applications that will very very very likely never be removed). SPECIAL NOTE: do not use silicone to bed deck hardware! 99.99% of the time silcone has NO PLACE for use in the marine environment! … More Do you know the condition of your boat’s deck hardware bedding?
