Rain today so no painting. Besides, need to get more gray POR-15.
Too many drips along the edges where the skins will clamp to allow a good fit. Sanded down with block sander and 80# paper.
Worked on how window opening trim piece will fit. Factory spot welded top of skin and frame. Not sure this is necessary. At most I might epoxy them. Both are wedged inside the window trim, so any additional fastening seems like overkill. Posted this question on Bimmerforums.
Details of rubber and felt inserts, which I removed. Rubber destroyed.
Finger pointing to where skin edge and frame edge meet along top of window opening.
Window opening trim in place.
