Yeah, there is a MAJOR weight issue there... it might cause me to have to re-balance all the aircraft I have used this sorry alcohol thinned stuff on... As far as strength is concerned, do you mind telling me exactly what strength has to do with using epoxy to FUEL PROOF? It's not having to support anything or hold anything together, so I fail to see your point, if you had one. I've had alcohol thinned epoxy on a couple my aircraft for way over a year, and nothing has gotten through it, and it's still plenty strong.

You know, lots of people have alcohol thinned epoxy on their firewalls. And the epoxy is cured. Or at least it seems to be cured. And it seems to be strong.
But truth is, the epoxy would have been lots stronger if it hadn't been thinned. And drugstore alcohol is what 70% alcohol, or if you spend another quarter, it'll be 90-something% alcohol. So what is the other percentage? And is it left behind when some of the alcohol evaporates? But so what....
If it seems to be strong enough to those people, good for them. One thing for sure, is that epoxy WILL be 100% as heavy as if it hadn't trapped whatever alcohol and "the other stuff" when it "cured" and whatever it trapped will be 100% as heavy as it was in the drugstore bottle.
This is another Ford vs Chevy argument, sort of. Really is more of a Mercedes vs Skoda argument however.
