When I got home today, I quickly finished countersinking and deburring the firewall parts, then after dinner I drove to work to get everything primed.
Here the parts have been scuffed and cleaned with acetone, and are ready for primer.
Finished priming. I left the parts to dry, will bring them home tomorrow.
When I got home, I deburred and dimpled the firewall and recess. Now everything is ready for assembly tomorrow!!
