Al was over today to help with some riveting. I mixed a small batch of Tank Sealant (as per the instructions) and applied it to the center / cooling ramp area of the lower edge of the firewall. Then we set the 6 rivets per side to secure the firewall to the forward floor assembly. Then I continued with work on the center section which entailed some match drilling, and machine countersinking parts for a half dozen platenuts.
