Epoxy by all means. Protect the hinge line though or you will turn the hinge into a board. I use dental wax and using an xacto knife and an Alochol lamp, to heat the blade, I apply a very light layer of wax on the hinge line. Do both sides. When you seat the hinges, wipe off any epoxy that ozzes out. Alochol on a paper towel works well for the clean up. I epoxy the hinges in the movable surface first, and then after it is set, then epoxy to the wing, or stablizers. The wax that is left acts like a lube.

Some guys use vasoline on the hinge line, but I like the wax as it is dry and doesn't rub off in handelling.
