We hit a snag and wanted your opinion. The tank sealant used on the original kit back in the early 90's is pealing off in the tank. We used a video snake camera to look at it and it is basically pealing off in big white sheets.

Last week the youth chipped with a coat hanger as much as they could and then vacuumed all of the chips out. I am going to take some of the chips and see what chemicals work to dissolve them best in test tubes.

Currently the tanks are sealed inside the painted wing.
