Just a bit of work today. I filled the "gutter" surrounding the right door opening on the cabin top with a mix of Cabo and micro. I then installed the door which has a 1/4" strip of weatherstripping around the inside perimeter to level the slurry mix. After it sets, I'll apply a second micro skim coat. I'll also apply a mixture along the bottom edge of the cabin door opening to establish the requisite 1/4" seal gap.
