So my 17 year old fiberglass pool need refinishing. Gel coat is about gone. That’s not my discussion. Have been quoted repairs from 2 different companies for repair. ( not much different in price ) 1 company does an epoxy repair. He says 5 to 7 year warranty. 2nd company does a re-gel coat. They say 7-10 years. So question is, does any have experience with either repair and thoughts?? Thanks Rick
