Got up early today to get the tank riveted. The first thing I found was that the proseal was a dream to work with as it had partially cured and was not sticky. The first thing we had to do was to clean the proseal out of the rivet hole before inserting the rivet with fresh proseal. riveting was straight forward but took a little longer due to the cleaning and re-prosealing process. After all riviting was completed, I came back and cleaned the outside of the tank as well as put a dobb og proseal over the shop heads to complete the sealing process. Next step is to complete the plumming and install the end ribs.
