Before I close off the trailing edge of the elevator, I have to varnish the inside of the skins that will never again see the light of day but will still be subject to moisture in the air. Following the advice of Dave Nason to put on a minimum amount of epoxy (less weight) but still have good moisture protection, I'll be using a squeegee to apply the epoxy in a really thin layer and will put on two coats to get a good seal. Today, I put the first coat on the inside of the bottom skins as well as the marked and taped off upper skins. It's hard to tell from these pictures but using the squeegee leaves a very thin layer. It just looks like the plywood is wet mostly, you can still see the grain texture. The next coat will also be thin but should seal off the plywood.
