NOVUS haze residual

[Diane Matten]

Hi, I sanded and buffed all the scratches in a 30gl acrylic tank, used NOVUS 3, 2, 1 system. Looked great. I then filled it with water and over the next few hours, a haze formed on the surface. I emptied the tank, used #1 again to rebuff, but still can't get some of the haze out. Also afraid to refill it (that's a lot of water!) only to have it re-haze. Any thoughts on what is going on?

One is just a cleaner it won’t get scratches out.. did you wet sand the acrylic before polishing it? It sounds like sand scratches but couldn’t give a honest answer without seeing pics of the tank and the problem areas.
