Hi
For the past year or so I have been fighting a weeping tank rivet on the top my QB tanks. I tried loctite but that didn't work at all.
Anyway, now that my wings are off for paint, I tried introducing proseal through the fuel sender hole.
After some discussion with a local A&P, I decided to drill out the rivet and replace it with a Cherry Max. Fortunately the wing was inverted on a table so I was able to use a vaccuum to draw out most chips as I drilled out the rivet. Next I opened the hole and hand countersunk it.
My concerns were that there would be a few small chips inside the tank as well the rivet might not completely seal even when coated in proseal. To deal with this, I introduced a couple of a small amount of proseal into the hole with a small syringe. I then installed a cherry max rivet that was completely coated in proseal.
A quick check today indicates the leak is gone!
Cheers
Les

I would have thought the gas would be greener on the other side of the border. 8^)

Not so much. I used a mallet to ease the bolts out and a couple of lifts to take most of the weight off the wings.
It was not much more difficult than putting them on. I had quick disconnects for wiring in the wing root so that was trivial. Likewise for the Pitot static lines.
That being said, I wouldn't want to do it too often.

How'd it go removing the wings? I've always thought that would be an enormous pain.
