I decided to fill the body tube / nose cone joint.
The tip of a older X-Acto blade was dipped in thinned Carpenter's Wood Filler. The blade tip was set in the seam and the small drop of CWF was dragged around the joint.
Doing it this way keeps the filler right where you want it and the blade tip guides the filler right into the seam.
After sanding down the primer, I had to add some more filler into some recesses above the body tube.
That filler was sanded down using a block.
This is a cast resin nose cone and not very porous so there isn't much for the filler to "grab" onto. I applied some thin CA glue with a Q-Tip to keep it in place.
After the masking tape strips were removed, the masked area was lightly sanded to remove any paint ridges.
The balsa reinforcement strips were glued down. Enlarge the picture and you can see how the center tick marks were lined up.
Under the two reinforcement strips in the picture is a wrap of paper. This is another way to guarantee all the bottoms of the strips are at the same height.
