I have a large and very strong retriever who has chipped my fiberglass stairs by standing on them and pushing off to chase tennis balls in the pool. I have three pea sized holes in the first layer of the fiberglass. They are not causing water loss however they look terrible and have fairly sharp edges.
Is there some type of white epoxy product I can use to fill them? I considered draining the water below the step and using white silicone just to fill them but I'm sure it would discolor quickly and probably not hold long. Any suggestions would be greatly appreciated.
