Greetings all, I was wondering if anyone here has any information or experience with vinyl wraps for wings, control surfaces, fuselage on sailplanes, It seems that this product would be pretty easy to use on ailerons, elevators and rudders and would be insignificant weight gains. Iknow that it is used in aviation. I think that the biggest issue may be static electricity and any drag resulting from dust adhered to surface of the wing due to static electricity

I would not even think about putting any wrap on control surfaces. The weight is not insignificant for control surfaces.

Concordia used film finish on control surfaces for weight saving.
That said just putting over old cracked gelcoat would be a poor decision.
