After installing the stiffeners to the fuel tank skins, Dad and I began sealing and riveting the tank ribs.
Proseal gets literally everywhere during this process, and it’s very difficult to keep tools and the surrounding area clean.
We set aside a special batch of clecos for the process, since even though we cleaned them with MEK after each use, you never really get the sealant completely out.
After each row of rivets was set, I’d go back and apply the remaining sealant to any exposed rivets, smoothing it out along the seam. Meanwhile, Dad would start mixing another batch of sealant for the next row. It’s definitely a two-person job.
Since we were anxious to get up to Oshkosh, we decided to stop on each tank after the interior ribs were riveted and sealed, and we left the end ribs and rear spar for a later date. I’m sure we’ll both be glad when the Prosealing is behind us!
