I use PRO-SEAL FUEL TANK SEALANT on the end plates and I think that works pretty well. I believe the issue is, the epoxy used to glue the leading edge to the spars at the factory was affected by ethanol in the fuel which caused it to expand and crack all along the attachment point on the spar. You can see the malformation on the outside of the wing where it was exposed to the fuel and expanded. I believe fuel is traveling down these cracks and creating small leaks. There is a product called PR-1005-L BUNA-N-SLOSH COATING sold by aircraft spruce that I'm thinking about using to coat the cracks in the epoxy at the attachment points. Has anyone used this sealer and have information on it's effectiveness? I believe the structural attachment of the leading edge to the spar is still very sound bu t want to stop anymore expose to fuel if I can. I'm also finishing up an update to the panel which includes 2 GRT Horizon HX displays and a new Stratus Mode S transponder that will make the plane ADS-B compliant. Hope to have it all ready to go by reunion time.
