A long winter (blizzards, extended freezing temperatures, and no car progress). But finally spring showed up with extended periouds of 60-degree-plus weather.
After some research, I decided I wanted to POR-15 the whole interior. I never want to mess with rust again... so I did the full prep / rust inhibit / paint cycle. Turned out pretty nice, IMO.
Also, remember the "hell-hole"? Here it is, welded, seam-sealed, POR-15 primed, and sprayed silver (not quite the same silver that the exterior will be, but, oh, well):
