We bought a clear coating and did the garage ourselves. The clear give a "wet" look to the concrete, had to add shark skin so that it was not slippery when wet. This also cleans up nicely. We purchased from Sherwin Williams, I think it was less then $100 for an extended 2 car garage with golf cart garage.
Hope this helps.
