That's the right tape but it's discontinued at Tower. May be able to find it elsewhere. Here's something in stock at Tower just in case.

The other tape mentioned should just be a vinyl tape that is included in the kit that wraps around the wing root to cover the gap that may exist. 99% appearance.
