My travelers leak very bad. I am going to be rebedding all my deck fittings. I also plan on filling all the holes with epoxy and re drilling them out. But a friend who helps me work on my boat made a suggestion and I am asking what you think. He suggested in doing all that you would nomally do to rebed the deck fittings but going one step futher. He said, why not use a rubber membraine ? Like a ice & water shield used on a roof. Any thoughts ?
