Worth the time and effort.
After proper surface prep and 6 applications, my badly sun damaged RV shined like new, with many compliments. However, after a few months under the cover, the fiberglass surfaces that were in contact with the occasionally wet cover in the Florida sun discolored badly, and will have to be wet sanded and the coating re-applied. Also, the polish does not hold up well where boat fenders rub against the coating, and it wears away in cockpit areas that are heavy hand traffic, like hatchways and around handrails. Overall a decent product, I will probably re-apply in a couple seasons.

Brings old paint back to life.
Best product for fiberglass oxidation. Tried many different wax’s and compounds. Poly Glow did what the wax could not do.
