Brief Description: R F/Tank: Rivetted stiffeners and drain plug
I first masked off the areas where I didn't want any proseal. I then mixed up a batch of pro-seal and applied it to both mating surfaces (i.e. the skin and the stiffeners.) I clecoed the stiffeners in place and proceed to back rivet it all as fast as I could (this being the first "real" pro-seal aplication, I wasn't sure what to expect or how much time I had). The back-riveting when very smoothly and quickly. I also riveted the drain plug fitting in place. After that, I carefully encapsulated all the shop heads with pro-seal and made a proseal fillet along the edge of each of the stiffeners. All in all, a lot simpler and easier that I expected
NOTE: I had previously had a fair number of issues back-rivetting so I thought I try it differently this time around. I bought myself a much bigger metal plate as a back-rivet plate and polished it up. I then place in on the concrete floor of my garage as the center of my work bench seems to have a bit of "spring" in it when back riveting. It worked like a charm - the back-rivetting was spot-on and I was very happy with the results.
Insulation tape applied to all areas where I didn't want any proseal
Stiffeners rivetted in place with shop-heads encapsulated with proseal
Proseal applied to shop heads in drain plug in such a way that water can always reach the draing plug
