This is an update for the past 3 days. I put some fiberglass lay-ups over the fwd and aft protions of the doors where the latch pins exit the doors. I had previously filled these areas w/ a filler, but one of them began to seperate from the Delrin block. So the solution is to wrap everything in a layer of fiberglass. After epoxying in the door windows, I was not happy with the seam between the plexi and the door shell. I'm going to leave this area painted and it is important to me that it looks 'finished' So.- Solution is to tape off the windows w/ fine-line tape and then apply filler and sand to a smooth radius that can be painted. Easier said than done, but hopefully worth the effort. another one of those Deems quirks that is not going to make the plane fly faster straighter of further, but if i dont' do it before Paint, I will hate myself forever!. A little tough to sand those small radii with short/fat fingers, but that done. I prepped both door interiors for priming w/smooth prime around the perimeter and the windows. The bulk of the doors will be covered by the upholstery 'shells' that I previously made, the perimeter will also be partially covered w/ door seal, so This may be a gret overkill- but I matters to me : )
