AVI Nike Tomahawk Build Part 18 Body Tube Prime

Before this picture was taken, the tube seams were filled with CWF mixed a little thicker than the filler used on balsa. This thicker mix stays in the seams better.
Both tubes were sanded to surface leaving the CWF filler in the seams.

Both tubes got a single heavy coat of gray primer.

This is the top end of the tubes, small pieces of masking tape were stuck inside the ends to keep out the primer over spray.

Top tube: I usually knock down the bulk of the primer, light sanding with 220 grit.
220 grit is used until the white layer just starts to show through the primer coat.

Bottom tube: I switch to 400 grit to take the primer down closer to the surface.
Enlarge the picture and you can see the gray primer filling in the remaining seam lines.
You can even see some of the yellow CWF in the seams.
