Thank you both! I guess when I look at the pool surface, I really have no idea what I am looking at. I know it's been painted, but I don't know the difference between the plaster surface and the gunite when I look at it, so I'd say what I see is the plaster then. I can see areas of white (paint) and then areas of dark brown with stones that are easy to see. Just below the tile there is an area that looks like light brown plaster and then below that is a very rough edge which I'm not sure if from the paint chipping or if it's bad plaster. I read a little on the other coatings, but wasn't sure what the difference was. I'd much rather do this once, the correct way, and have it last longer - than do it a cheap way.
Chris - it was 1.4K total for the resurfacing, or was that just for the addition of the Pebble Sheen? We need a resurface and some tile and coping work done. I was quoted around $8,000-9,000 just to resurface and another $3,500 to do the tile and coping. It's not that large of a pool!
