Estes Constellation Build Part 12, Primer Sanding

Here's the body tube and nose cone after the primer filler was sanded down.
The nose cone was slipped into the body tube for primer painting.
The clear payload section will be trim painted later.

The fin and fin pod transition joints looked pretty good after spraying with the primer filler.
The primer was sanded with 400 grit.

There is plenty of inside edges that need to be sanded.

TIP: Here's another use for the Q-tip swabs.
Roll a piece of 400 grit around the cotton tip.

This gives you a small, round cushioned sander with no sharp creases in the rounded end of the sandpaper.
