I have found that mine tend to get stolen before they reach the state of needing repair because once I find one that catches fish and I like using, I tend to stick with it until it gets busted off, but half your luck if you have some of sufficient vintage to warrant repairs! 
I'm with you on that for sure! All of the legend lures are now no doubt floating somewhere between here and Mexico!
The two things that I am mostly concerned with are restoring or patching the finish on my molded lures and keeping the water out of my wooden ones.
I find that my Fisherman lures are quite soft and a decent sized fish will penetrate well into the wood and once they get waterlogged they get heavy and the way they sit in the water changes.
I also use a lot of Japanese molded lures (generally gifts or samples - the brand names I cant remember), these lures work very well generally and dont take on water BUT their finish almost always comes off either in scratches or chips once a few bite marks converge. I have found that when the paint is really bad (ie showing a lot of white) the fish often decide at the last moment not to attack, hence this topic.
I was thinking of trying some glittery nail polish
to seal individual tooth holes (and maybe add some flashes), has anyone tried that?
For the bigger jobs I will try out the epoxy and see how it goes...
