I am refinishing a dining table. I started with 2 coats of primer, 4 coats of Benjamin Moore Advance paint in black and then followed up with 6 coats of Varathane water based poly on the tabletop. I applied the coats of poly over the course of 4 days and then let it cure for 7 after the final coat. I did sand after every 2 coats. I purchased the Micro Mesh system to rub the finish. I started tonight and sanded first with 400 grit regular sandpaper (as per Micro Mesh's instructions) and then I only made it up to 2400 Micro Mesh wet sanded with water and dish soap and now I have what appears to be rubbed away the poly in some areas. If I rub in some of those areas, I get black on my cloth which I am assuming is the black paint. Is it possible that my poly wasn't fully cured and I rubbed away the poly? I tested it out and rolled on a little poly over one of the areas that looks gray and not black and even with the wet poly on it, it still looked gray. Help. I am about to cry because I don't even know what to do to fix this. I have worked so hard on this project and I'm afraid I ruined it.
