Aldo,

I usually use 30 min. Epoxy thinned down 33% with denatured Alcohol (1/3 alcohol + 2/3 Epoxy). It works best to put on two thin coats. Cover the entire area with the first coat and let dry overnight, sand with 400 grit sandpaper to a nice smooth finish, and apply another thin, even coat.

or...

just paint it with fuel-proof dope, you can get clear dope at any hobby shop and apply it just the same way as epoxy, only use dope thinner to thin it.


Hope this helps, it always works good for me.
