Yeap.
Tower has this stuff in stock which you can cut down as needed.

The wing "sits" on the two vertical portions of the fuselage.
When the rubber bands are applied, the wing and the fuselage contact each other exactly where you want to put the tape.
Place the tape on the fuselage side, not the wing. The tape is single sided sticky tape, so it will adhere to the fuselage "walls" right on the edge.
It has two effects.
1 - It prevents damage to the wing and covering.
2 - It helps to prevent having the wing move or slide while in flight.
I put it on my daughter's trainer and the wing does not shift in flight as some have reported.
