New pool owner, 40 x 20 Gunyte pool, painted 5 years ago over the older plaster. Time to resurface, I have had a bunch of different contractors tell me many different things. Was leaning towards trying to up the budget enough to have a pebble Tec resurface done. Have another guy telling me that his fiberglass Gel Coat is the way to go, it will last forever etc. unsure of what to do, reading all kinds of different things. So the question is an older Gunyte resurface, I don't want to Paint again, so what is best, Plaster, pebble Tec or should I be considering the fiber glass gel coat? In the New England area of that matters. Any helpful advice is appreciated, it is costly and I am just trying to make the right decision. Thanks.
