Q.For gluing exterior wood trim components that will be exposed to the weather, but not submerged under water, what’s best: resorcinol, epoxy, or a polyurethane glue?

A.Any one of these will work, as long as the joint has good wood-to-wood contact. Personally, I think that epoxies and resorcinols have the best outdoor endurance qualities. For those joints that may be a bit loose, epoxy is the best, as it has the best structural and gap-filling qualities.
