Even though I am quite a newbie myself, I may be able to help here. What I used was some 30 Min. Epozy mixed with Denatured Alcohol. Now, the only painful part about this is having to purchase a whole can of Denatured Alcohol for the 1/32 of an ounce that you need to fuelproof the plane!

Also, after doing that, I put a coat of Sig Fuel Proof Paint (Black) over it, for added protection, and it looks real nice.
