Urupema wings and elevator: sanding the glass and applying filler/primer

The 49gr glass covering wings and elevator hardened out nicely, and I couldn’t help putting the plane together to see how it looks, now also with the landing gear :-).

Today I sanded the wings and elevator and cleaned them. After that I applied the primer/filler. First with a roller and then pulling it deep into the (few) pinholes using a spatula. I hate this part, as the primer stinks like hell. While it needs around 20deg C to harden out I cannot apply it outside, so I spent the morning in the workshop using a face mask. Now the primer can harden out over the weekend. On Monday it’s sanding time again….
