Re: Stainless nuts bolts in Aluminum boat

Sikaflex products are what you want to use for bedding and sealing compounds above and below the waterline.

When I worked building waterslides, every stainless 3/8" bolt holding the tube sections together was given a dab of Sikaflex to prevent galling while being tightened with an impact wrench. Out of the thousands of bolts used, I can only recall one which jammed while being tightened. Since we couldn’t get it undone, it’s still in place, right where we left it.
