Iím determined to keep the mess to a minimum on this tank. I cut a hole in some typing paper and taped it to the tank around the fuel cap flange.

On the other tank, I just put tape over the rivets and left the hole open. The result was a huge proseal mess all over the back-riveting board. This time the rivet tape is going to trap the proseal on one side of the tank skin.

Same song and dance here. The typing paper and painters tape will keep the mess to a minimum.

I pressed down hard on the back rivet tool to make sure that the curved fuel cap flange laid flat against the skin and back-rivet plate. I used a paper towel with some laquer thinner to clean up the excess proseal and forced the excess into the crack between the skin and the fuel cap flange to assure a good seal.

The painters tape and typing paper make cleanup a snap. The small curled T-914 clip was a real pain in the bahootie to rivet. I had to drill it out twice before finally getting it right. I ended up using my 4 inch yoke from Averys to put this one rivet in. The back-riveting on the rest of the rivets was easy.

I pushed the rivets into the holes one at a time and squeezed them in place with my 4 inch yoke and hand squeezer. The proseal oozed out everywhere, especially in the screw hole in the middle of the drain flange. I cleaned everything up with a paper towel and lacquer thinner. To clean out the screw hole, I rolled up a piece of paper towel and forced it through the hole and pulled it through the other side, turning it as I pulled it through.

I dobbed proseal on the rivets on the inside of the tank skin.

The instructions gave me the choice of creating a cover plate to rivet on or squeezing a really large rivet into the hole. It just so happens that I have a "bucket o' rivets" that I got from another builder that has already completed his RV. I found the perfect size rivet in the bucket and squeezed it into the hole. I made sure that the hole already had some proseal in it before the squeeze. Then I put an extra dab of black goo on top of the rivet, on both sides.
