Poly Dope Question

Wanting to spray two fabric covered wings. The fabric is very good still.
Silver dope all over from little repairs. Rebuilt airplane - one wing Stitts,
one Ceconite.

To the question: Is there indeed a plyurathane (or some other) dope that can be
sprayed and adhere to both types of wing covering, just to get us to a complete
recovering next season?

Thanks in advance for any product recommendations, ideas and experiences.
