Snuck back out to the garage after work and primed the forward floor parts so I could start riveting. It was 60F and I managed to out there after it rained so I don't get held up waiting on conditions that are condusive to priming. I didn't prime the top of the floor as I plan to 2 part epoxy prime the interior of the airplane for durability and I'm not sure if the 7220 is compatible - I need to reseach this.
