We found cracks in gunite which were obviously patched in the past by the previous owners. We knew we were on borrowed time with our pool as it is 30 years old and has never been refinished! Ideally, we would like to patch to get us through the rest of the summer and then look at resurfacing over the winter. We can't decide if we want to go gunite again or one of the Pebble Technology products (Pebble Tec, Pebble Fina, Pebble Sheen, etc.) and were wondering about others experiences.
Also, any tips/experience you can share about patching is also appreciated.
