Looking great! At least in my case, the blotchiness appears to have decreased a good amount, but it is still there. I'm about 3 weeks in since filling, brushing daily(but we did alot more than that the first week).
They mentioned dropping the pH way down for a day or two to improve it more if I wanted. I've seen a friend's pool plaster etched and basically destroyed by another company doing the same thing. Actually it was his service company...(long story.) So given the risk/reward ratio, I think we're about where it doesn't make sense for us to put the new plaster through that.
Every time I look at your thread I have total spa tile envy. Makes me want to rip mine out and do it again.
