The front seatback locations where it mates with the fuselage side were sanded and vacuumed.
The seatback clamps were removed.
A piece of wax paper 8″ x 31″ was cut and lines drawn at 2″ intervals.
Two pieces of BID cloth (at 45 deg orientation) were cut to fit over the wax paper.
The cloth will be cut into four 2″ x 31″ strips to be used as BID tape for the seatback joints.
