So I'm cleaning out an old 50g Acrylic that I'm going to use, I used 800 and 1500 Wetdry sand paper (Home Depot didn't have any 1000 or 2000) since there were a ton of scratches and polished it off with Novus 1, 2 , and 3. It worked out really well, about 95% of the scratches are gone, but now I have these wipe marks which I believe might be from water I test filled the tank with, does anyone know how to get rid of them?
