rather discouraging,as it was claimed that sloshing compound would block fuel lines.filters and pumps
++++++++++++++++++ Dankie Bwana When I was refurbishing my Cherokee 6 I spent a great deal of time researching the Sloshing compound available for certified aircraft fuel tanks. I think that there was only one product available - may be wrong there Eric. There had been reports of the problems you refer to, but I soon found out that the folks who had the most to say had never used the stuff. I came to the conclusion that problems were encountered by guys who did not read the instructions - in particular the preparation of the tank. Some of the problems were caused by metal tanks that had been sloshed in a previous attempt to cure a serious leak and not treated /cleaned before the second attempt - in short, the new compound was applied over a bad prior job. Consider doing some tests on a glass panel of similar material (and rigidity) and see how well it bonds. In your case it would be well worth the trouble to gain both wing tanks. >From what I heard from some 20 guys who had used it, I would have no hesitation in using it on a glass tank (epoxy or polyester). I do not recall if the instructions addressed the application for non-metal tanks, but I do recall that my Boere Boeing tip tanks were composite (Almost sure it was a polyester resin). AS things turned out, the coatings in all 4 of my tanks were in good shape, so I never got to use the stuff. Take care Steve J
