Fortunately, I haven't had any weeping rivets. Here's what we do with steel motorcycle tanks:
1) Drain fuel and rinse with water.
2) Slosh with Marine Clean for a while.
3) Slosh with Metal Prep for a while.
4) Pour PUR-15 sealent into tank, rotate until it is evenly coated, then pour out excess.
Unfortunately, sloshing an entire tank probably isn't a good idea for the RV-10. It would be heavy and I'm not aware of a suitable sealant for this. If you can reach the leak through an access hole, that would probably be best.
For a difficult to reach leak, I wonder if it would be possible to drill out the weeping rivet. Then, inject a little thinned proseal with a syringe and replace the rivet with a suitable blind rivet.
