I have a 2005 RV9A and I have one rivet slightly oozing fuel on the top side of the tank. You cannot even see it but after a flight you can see a short trail from that rivet. It is temping to just forget it but I want to attempt a simple fix. Turn off the fuel valve, drain the tank, connect the shop vac to the tank filler. Pull a vacuum on the tank, being careful to avoid any skin distortion. Then place a small amount of thin selant around the rivet and wait. The question is, what sealant is going to be thin enough to pull into the joint and still be fuel proof? Any ideas? I cannot get to the backside of the rivet to Proseal it.
