A few years ago I had a leaking rivet on the underside of the left fuel tank on the RV-7A and Doug Weiler of the Twin Cities Builder's Group suggested some ProSeal and a closed rivet. It worked great.
For the last couple of years, I've had two nagging rivets on the top of the tank which, when the tank is full and pressurized, emits just enough fuel (and it's not much) to put some streaks in my nicely polished plane.
This was one of the tasks to put off until annual and this week I started on the annual condition inspection, vowing that this one would be the most complete yet.
So I took the tank off . I didn't have to; it easily could be repaired without doing so, but the underside of a polished fuel tank and inboard wing gets beaten up, so this would also make it easier for me to polish it up on the underside while working at the workbench. I'll probably do the other side too ... polishing, I mean, there are no leaks on that side.
