Refurbishing a 69' Highlander with a teak rub-rail. Teak came out good after sanding and refinishing. Going to purchase new fastners to finish off the look. Question is do i use any type of sealant (silicone?) on the top and bottom of the rail where it meets the fiberglas body? I assume there would be no adhesive on the back-side of the rail being that it has about 20 brass wood screws down the length of the boat. It didn't look like there was any adhesive or sealer on the back-side of the rail when I took it off but it could have disappeared with age.
Thanks for the help!!!
