Estes Alien Invader #3003 Build, Part 8, Wing Tube Fill and Paint

I filled the inside seams of the Wing Tip Tubes, part F.
The interior of the tubes will be visible on the finished model. They will be painted red before gluing onto the wing fins.

The outside surface of one tube was wrinkled. A little sanding with 400 grit brought it down slightly. Filler/primer will remove the rest.

All three tubes were joined with the coupler and the 24mm casing on the painting wand for a shot of primer/filler.

After everything dried it was lightly sanded to surface with 220 then smoothed with 400 grit.

The outside of the individual wing tip tubes were masked off and the interior tube walls painted with a white undercoat then fluorescent orange/red.

It's easier to paint the inside of the tubes now, before gluing to the wing and spraying the main body black.
