Default Help! Polycrylic Disaster

I recently completed a Hog Bipe and covered the airplane with Wordtex iron on fabric. Had read where that a lot of folks apparently use Minwax Semigloss Polycrylic as a sealer for the covering. Newbie that i am, i though keep it simple. The research is done and hammer down. I used the spray can method for application although some people recomended airspraying with a drying control additive. It went on nicely and was applied on an average to low humidy day here in the Deep South. All parts were allowed to cure for a full month while the project was completed. Glow powered airplane, running 15% nitro. .

Now I had read that a few folks had experienced some gummyness which some had had concluded was a result of not letting it cure long enough before fuel exposure or allowing fuel to stay on it too long. I think in one thread some one specified to get fuel residue off within 4 hours and then also added that any gummyness that resulted from leaving fuel on too long would go away in a week or two and the material would reharden. But nothing had prepared me for what has happened. The mess is disolving.

I would like to say that the advice of using this stuff might be correct maybe in a desert enviroment, but it dang sure is NOT true for my world. Every where fuel has even thought about touching is either in the process of either being a gummed up mess sucking up dirt or has disolved completely away as in the case of the forward fusalage bottom.

So that is where i am and i need some help in figuring how to get this mess off my apparently ruined beautiful coveing job. I have entertained the idea of spraying the whole airplane with 30% helo fuel and letting it soak for a day or so. There is two coats of that canned crap on the Hog, and one can only imagine trying to rub the resulting sticky sludge off the covering of the open structure wing areas and in particular delicate areas like the interplane strut mounts. Any suggestions on a solvent that won't eat the fabric or it's adhesive? I really nead some help here guys from someone that has been in this trap.
