"2. Can I epoxie the foil whenever possible?" To protect it, yes. To join segments, no. Simplest way to join segments is probably to make a french seam (like blue jeans legs) and hold that away from anything flammable, then use a small torch and electrical solder (not plumbing solder) in the joint.
It would probably be much cheaper, and just as effective, to simply paint over the foil with a good paint or synthetic varnish, i.e. a urethane base product, instead of using epoxy.
