I am going to drain and acid wash my pool once the season is over. If the stains dont come out I want to get the plaster redone. But here lies my problem... There are only two pool companies in the town I live in one gave me a quote of almost $8000 which I believe is extremely high and the other came out but never got back to me with a quote...I don't trust either one of them... So I ran into this Pool epoxy while searching the web and figured I would get opinions on it here.
