With all the longeron hassle behind me, I got back to finishing up prep and priming of the firewall angles and F-705 rear spar attach bulkhead parts. I decided to try a new primer on these parts, since they’ll be top-coated with interior paint. The new primer is chromate-free, which makes it a little easier to handle. It’s also available locally, which is a bonus. It’s not as durable as the fluid-resistant primer I’ve used, but it’s a lot safer.
