Some folks have had success with drawing a bit of loctite (green i believe) in through the rivet from the outside and a tiny bit of suction. Search it here on the site.
This was a process I documented several years ago, but used pliobond.
But yes, others have had success with loctite.
My bottom tank rivet has not leaked after 5 years.
Here's my original post from 9/5/2012

BTW, My plane's been flying 6 years and this developed yesterday.
Strange how these things crop up out of nowhere.
I'll provide an update when available.
This is an update on my original post.
Seven days into my fix of a weeping rivet, problem solved...
As stated above, I used a a syringe with a 1/2 diameter barrel. I cut & removed the needle mount to expose the 1/2" opening. I made sure the cut was clean & symetrical to allow a perfect seal when placing over the skin & weeping rivet. I used Pliobond as it has a slow cure and is chemical & gas resistant.
To begin the process the fuel level must be below the weeping rivet.
1. Remove the fuel cap.(this will allow a pressure variant)
2. Load a small amount of pliobond into the syringe.
3. Place the opening cut end over the weeping rivet and make sure you have a solid seal against the skin.
4. Depress the syringe. You should feel resistance if you have a solid seal against the skin & providing the push.
5. Repeat step #4 to insure enough pliobond consumes rivet.
6. Let cure for 48 hours to ensure proper seal.
Others have suggested green loctite, which may be a better product. But, I happen to have pliobond that I had previously used & was recommened by Lycoming for crankseal sealing.
Hope this works for your situation. It's a low cost alternative to what others have suggested. Now I just have to come up with a way to remove the blue fuel stain.
