The floor came out great - we used U-Coat It. My wife and I did the work.
700 ft sq, on new concrete- although it cured for about 2 months. Wash, acid etch, epoxy coat 1, fill cracks and holes, epoxy coat 2 with flakes, final urethane gloss top coat. Pro- You can spill anything on it, it just wipes up. No concrete dust. Washes easily. Car tires or car dolly tires don't mark or pull up coating. Con - dark floor with flakes sometimes makes it difficult to find small parts on the floor. Sharp edges can scratch the urethane top coat.
All in all very happy with it and it looks great.
