2" wide fiberglass tape can be applied to the wing center joint (top and bottom) using the following method:
- Cut the tape to length - one piece from trailing edge, around the leading edge and back to the trailing edge.
- Lightly spray one side of the tape with a spray adhesive such as 3M "77".
- Center the tape on the wing center joint and press in place all the way around the wing.
- Flow THIN CA glue into the tape with a side-to-side motion. As the glass tape turns clear move down the tape until the complete length of the tape is glued. Remove any extra glue with a clean rag. Try not to flood the tape with excess glue as it will cure quickly, causing bumps and snags in the tape - bummer, more sanding.
- When the CA has cured, sand the joint lightly to remove any rough spots. Try not to sand into the fiberglass tape itself.
I just followed the directions.[/TD]

You did not work on the wing saddle area which is on the fuselage. You worked on the wing joint.
A chain is only as strong as its weakest link; in this case the layer of 3M "77".
My previous posting is still applicable.
Perhaps some other fellow may help better than I.
I would have questioned these instructions.
Merry Christmas
