The work effort was now broken into two teams, one applying finishing tapes and "Polybrush" to the wings, and the other cementing the covering to the fuselage and tail surfaces. Polybrush is a dope-like, fast drying paint that fills the pores of the fabric.

The fuselage was turned upside down and the bottom and side covering applied in the same manner as the wings. It was then turned right side up and the top covering applied
.

The first coat of Polybrush was applied using a brush. Because of the wide capstrip on each rib, there was little need for ribstitching but we felt that the students should see this process. Ribstitching was performed on the wing ribs at 6-inch spacing with the students tieing most of the knots.
