Resorcinol has the track record and is the only glue that will take extremes of wet and dry, heat and cold.
Epoxy has very limited exposure outside and has been known to disintegrate even if maintained. See the renovations that had to be done to all those traditional finished cruisers from 20/30 years ago - especially anchor platforms and bowsprits.
Epoxy glue is an interior glue! It can't take heat (it softens) and can't take cycling because it doesn't move. If you seriously have to keep exposed wood together, there's definitely 5200.
