After 5 years we have to reSurface our pool. We had a blue Diamond Brite finish which has become a dingy grey. So after reading posts here and asking the lady who takes care of our pool, we are going to go with the unpigmented finish. i like the Marquis Sapphire…Question…my PB told me Marquis has a 10 year warranty vs the Crystal series which is 30 year…has anyone done the Crystal and can I see pics?
