Fuel Proofing RC Airplane

I am trying to find out which balsa glue is fuel proof. And, is there some sort of sealant to coat the whole frame with before covering my model?

No, use epoxy rubbing alcohol mix
by: rcdude07

No glue will do this. The best and long term used solution is 30 minute epoxy thinned using rubbing alcohol.

You only need to fuel proof the following areas for sure:
inside fuel tank compartment
firewall
landing gear mount if under the fuse not on the wing.


Anything more adds too much weight. The covering like Monokote will take care of the rest of the plane.
