Creating some scarfs with White oak rails on a dinghy and looking for techniques folks have used for gluing and their opinions of how those held up. I was going to use a 12:1 and hand sand with a board to get a flush tight fit (rails are curved).

What I've done in the past is used epoxy, and no special preparation, and that worked. Some are still perfect after 15 -20 years or more. I've also used resorcinol - but realized I currently don't have any. Is there special prep I should be considering if I think the area is likely to be under some stress?

Thanks
