Uncertain as to their cause, I finally took a razor blade and cut one off. It was filled with fuel. Apparently I had several pin point leaks on the top of the tank. The timing was consistent with California outlawing the MTBE additive and substituting Ethanol. Cause and effect - pretty suspicious. I re-sloshed with the oft maligned Kreem - after removing the factory Kreem with Acetone. For the next three years using California's 10% ethanol reformulated fuel, except on cross country trips, I had no problems with leak issues. The airplane was destroyed in our not so perfect emergency landing near our home ten minutes into our flight to the 2007 factory Fly-in - explanation for the short only three year history.
Pics of the wing support I made to enable wing removal and sloshing with minimal effort. The attachment of the wing tip to the support was a fully mobile gimbal for unlimited movement and the inboard support folded out of the way for manipulation of the wing.
