How can you repair cracks and clean the gel coat on AquaSlide N Dive brand fiberglass slides?

Check with a boat company. They have many product to repair fiberglass.

Oh boy, I wouldn't want my kids sliding down an old , repaired slide with a possibility of getting a fiberglass chip or sliver rammed into their leg, hand, arm or butt and possible removing a good chunk of skin. No indeed. Too much liability. Even a new slide is a liability. For the cost of materials and your labor( what is your time worth) consider if you will ordering a replacement chute. I would inspect the stand's leg supports anchors, water feed, ladder, grab rails and other parts for soundness before ordering replacement.
