Hey Guys,



I almost have my old wing tank removed. Only problem is that the tank has no gap between the tank and the front spar. The rear spar had a lot of room and I was able to use some safety wire to work through the silicone and it's separated but the front spar is so close to the fiberglass with no gap that I can't fit even some .020 safety wire to cut the silicone. I definitely don't want to pry on the tank because I don't want to damage the spar. It's very tight and I can't use a screwdriver or a paint scraper, only a razor blade is able to slide between the fiberglass tank and the spar but there is no mechanical leverage to persuade the tank in to coming loose. I don't want to go at it with a dremmel because if I nick the spar, it's done, replace the spar and rebuild the wing. As much as I want a nice shiny set of freshly covered wings. My bank account doesn't.....

It seems that the only solvent is Xylene (Strip-Rite @ HomeDepot) that will soften the Silicone.



Has anyone had a tightly fitting wing tank? What did you do to get it out?



TLDR; silicone adhesive and a tightly fitting wing tank won't budge. How do you remove a tank without damaging the spar?



Thanks Guys,
