All my bad. Didn't wash the sprues, no primer, just MM Acrylic. Theblack had a week to dry/cure too. Used Tamiya tan tape and killed it on pants and shirt, but not quite enough I guess. When I repair I will soft mask the upper edge with post it notes. They didn't lift on the other hull I am using as a test bed.
Probably going to have to get another '41 or '42 version for the 3rd 20mm that Wahoo carried.
