Ed. looking really good.
About that windshield seal thingy: I used to use RTV/Silicone for a wing/fuselage gasket on my radio-controlled airplanes. I used plastic wrap/Saran wrap on one side(the wing). Silicone the other(I'd silicone the bottom of the windshield), install, leaving it tight but not fully tight. After the silicone sets up, remove plastic and trim the silicone edges with a razor blade. Removable, reusable, and most important, it seals AND looks good.
