Well I'll use this thread to ask wat is the lightest material to protect from water/fuel/oil?
Until now I have been using the GREAT PLANES Finishing Resin. Would love to hear about new stuff. And what exactly is balsarite?
Balsarite is a heat activated adhesive. It is designed to be used with coverings that have poor or no adhesive on them (such as Coverite fabric or Koverall ).
As a "side effect" is also helps seal the wood.
I would suggest using the following to protect from water/oil/fuel:
1 thin coat of a commercial sanding sealer. Ideally, sand the fuzzies off when dry.
Follow this with a thin coat of polyurethane.
Oil base polyurethane is FUEL PROOF.
Water base polyurethane, while lighter than oil base poly, is FUEL RESISTANT. As long as you clean the residue off at the end of the day you will be OK, but if you leave it on overnite (or longer) it will soften the poly.
In any case, either of these will definitely be lighter than resin, and both will do what you want - keep the insides from absorbing water.
