Each tape going over the wing ribs is 2” wide. Before taping the ribs you need to mark each rib to keep the tapes straight and to apply poly brush in the right spot to secure the tapes. I found some drywall tape that’s 2” wide with a crease at the center, which allows me to mark the 2” widths with my pencil, center the tape on the rib center, and apply the poly brush in the right spot. This cuts down on a lot of time marking where the tapes go.
A roll of tape costs $1.99 at Menards

P-K screw rusting. The top of the screws always look ok. It’s when you loosen it up where you get the rust under the screw head. All of them are being replaced like I did on the other wing. All the screws are out and corrosion prevention applied under the leading edge.
