Last night before going home I mixed some pros-seal and filled the joint between the canopy ribs and the instrument shelf and firewall. I also put s dab of pro-seal on the heads of the rivets on the upper firewall. I put pro-seal on the lower rivets some time earlier. The pro-seal in the joint looks pretty good because of the masking tape. I pulled the tape off this morning. I will mix some more pro-seal and seal the upper firewall at the upper forward fuselage skin attachment.
