Semroc (Centuri) Excalibur KV-43 Build, Part 4, Filler Primer

The fins were sprayed with filler/primer before gluing onto the body tubes.

On the left is one of the larger, lower fins after sanding down the filler/primer. The remaining gray filler shows how uneven the surface is.
On the right is the small upper fins, before and after sanding to surface.

The balsa nose cone and adapter were rough!
I did have to build up the shoulder edges by brushing CWF filler over the edge and quickly turning it against the body tube edge. This picture shows the raised edge bead after it was pulled out and away from the tube edge forming.






I used a sanding block to get the sides of the adapter flat. Apparently the adapter sides were a little rounded, I sanded through to the raw balsa!
This required another round of filler and sanding. The pencil marks outline areas needing attention.

The body tube seams were first filled with CWF and sanded to surface.

Here's the two sections after spraying with Duplicolor Filler/Primer. This will fill any seam that remains.

I shot the model in two sections. Tall models are difficult to spray evenly. It's easier to hit them in shorter sections.
