My father just coated his 27'x 57'(no that's not a typo) garage floor with U-Coat-It or something like that. It's been on the floor for about 8 months now. The stuff is great. My only thing I don't like is when it is wet, just water wet, it IS SLICK. We even used the sand they supply, which made a huge difference, but still too slick for my liking. You may also need a dehumidifier if this garage is part of your house. I never realized how much moisture in the air was absorbed by concrete until we finished the floor and it was always damp.
