Alcohol and epoxy, 30min. #1, Straight finishing epoxy, #2, Dope #3, that's A lot of CA?? And I have tried the Poly U paint once with good effects. Thinning the Epoxy with Alcohol has always been my number one go to and it has worked out well for A lot of years. I had A couple of large bottles of finishing epoxy and tried that and it works fine. Sometimes the Dope is hard to find. Isn't that statement leaving the door opened. I only tried the Poly paint once and the plane is still together without any oil soak. I have just used the Klass Kote paint for the first time, painting A plane, not fuel proofing, this stuff is so tough I tried to rub it off with Acetone and it didn't even remove the shine so it or the old K&B two part epoxy paints would be A great fuel proofer and it comes in clear too. Price is A killer though.[&:]
