Tape for sail track

[barrybrown]

I'm adding some 7/8" external stainless sail track to my mast, does anyone have any suggestions as to what is the best tape to use to isolate the track from the mast? Thanks

Don't know where the knowlegeable guys and sals are. Why couldn't you just paint the back side of it? The part that will mate the mast? You're trying to insulate the galvanic reaction, right? Or am I off base?

Without overthinking it, I'd probably use electrical tape.

Thanks for the suggestions, I set the track yesterday using 1/2" waterproof adhesive tape, the kind you get at the drugstore. Of what was available it seemed to have the qualities best suited for the job.
It may indeed be over thinking but most things added to the mast will be there for the life of the mast and exposed to the elements therefore I make a serious effort to isolate any dissimilar metals. There are over 100 machine screws holding this track set with red loctite so changing the tape would not be easy.

WOW! that sounds like a LOT of machine screws. That should definitely hold that sucker in place!

Okay I know this is an old thread... but how about some UHMW tape like this... 5 mil x 3/4" Seems like this would be perfect.

In case anyone else has the same question.

Obviously the initial person is done, but since the thread came back up, I would also use something like Tef Gel on each of the fasteners (to help isolate them).
