RE: fuel proofing?
The thinned epoxy is fine or a polyurethane spray.
Even though the problem isn't as bad as with glow. Oil is Oil no matter what it's mixed with, so you should fuel proof.

RE: fuel proofing?
You have to kidding - right? You have $600-$1500 invested in an engine, maybe another $500-$1000 in electronics, another $600-$3000+ in an airframe and you are worrying about the $.30 cost of epoxy to fuelproof the firewall?

Nothing wrong with thinned epoxy EXCEPT that it's alot more ($$$) than a clear POLYURATHANE that you can get at any K MART,WALMART, MENARDS or any hardware store.That's right-it's cheaper & works just as well.
And when your muffler comes loose you will find out why it's a MUST to seal raw wood with the epoxy or polyurathane.

Actually I submit that polyurethane if a LOT more expensive a solution than epoxy. We all use epoxy all the time, but a pint (or quart) of polyurethane with a limited shelf life? If you have no other use for it, the polyuerethane will go off long before you use it up. At $7 a pint that's a pretty expensive solution.

Minwax "Fast-Drying Polyurethane",1/2 pint(8 fl oz.) $3.75
A quart is $6.04...a good deal if you're also re-finishing a chair or if you're building 300 planes. Spray can(11.5 fl oz.) is $4.75
Other brands are a little higher but still cheaper than the epoxy.
Tower Hobbies Epoxy is $7.99 for 9 fl oz. Cheapest I've seen.
You're right about the limited self life,the urethane in the can will harden up in a few months.
The Polyurethane straight out of the can still get's my vote.
