I riveted platenuts and stiffeners to the forward baggage floor and bulkhead. I had to take some time to tape off the frame of the firewall so I could re-prime it in grey. When I primed it green a while ago I didn't realize this area would be visible when the forward baggage door is open or when seated in the cockpit looking down and ahead. Don't make the same error; it wasted a couple of hours to fix.
