Getting ready to proseal the ribs in
One of the things I dislike most about prosealing and riveting ribs is the cleanup afterwards. If some of the proseal gets anywhere on the tank where you don't want it, it takes some major rubbing with laquer thinner to get it off. I can see why proseal is used to prevent leaks, this %^&* stuff really sticks to whatever you put it on! (including yourself). Here I'm putting full sheets of the typing paper between the ribs and taping them down with removable painters tape. Only about 1/4 inch of the tape is actually sticking to the tank, the rest is stuck to the paper. The word "removable" is not necessarily an accurate description of this tape. When the rib gets riveted in, the paper and tape are removed immediately and pitched in the trash. No muss, no fuss and the rest of the tank is spotless.
