Surface of hot-tub damaged by UV

We installed outside 8 years ago. There is a film which is lifting away from the fibreglass shell on the areas most exposed to direct sunlight. Does anyone know of any products such as a spray-on resin which I could use to repair these areas? Thx.

Thanks John. I've looked up Gellcoat and it looks like it is just what we want.


There is a member of the pool group who sells Hot tubs, I would hope they would help you? Have you tried any of the fibreglass/polyester pool manufacturers?
