Screwed the upper cowling to the wing table and sanded the crap out of it, mostly 240g wet.
Happy with the shape, but the oil check door is bugging me. it is not centered properly and bulges in the middle under the opening spring tension. The hinge seems to have been contaminated by resin and is a bit stiff. As it stands there is no way to remove it without a drill. Hmmmmm.
