This evening was a quick one, flipped over the stiffeners that I primed yesterday and gave the underside a coat of primer. It was too cold yesterday to consider spraying both sides, so I left the parts for a day to properly dry before painting the otherside.
I took a close up of some of the #30 dimples in the firewall, this should come up quite nice once it has been flush riveted. But before I do that the stiffeners still need a coat of two pack white for that finishing touch and to blend them in with the rudder pedals.
