The proseal on my lhs wing inner rib has gone totally sticky [can smear it off with a finger] after flying with a leaking tank for 2 months. The wings are quickbuilt and the inspection cover was leaking. Avgas has leaked onto the factory applied proseal on the bottom of the inner rib. [just below the cover]
I queried this with Vans and they said that the blue dye in avgas and oxygen cause the proseal to soften. I cannot argue with them, but they couldnt explain why this happened.
The proseal that did not have fuel leaking on it is ok.
I know I should have attended to the leak sooner, but flying was more important at the time. Had I known I would have taken care of it sooner.
What I still dont understand is why the proseal went totally soft. Can anyone explain ??
