Another guy in the mid Atlantic crew (MightyBobo) made a nice write up about how he did his garage
To Make a Garage
I plan on also finishing my garage but am waiting til the ambient temperature rises. The epoxy and etching chemicals want to be applied when its 50 degrees(f) or higher. Also need to make sure your floor is extremely clean, no oil marks and the chemical used for that is some potent smelling shiet. My biggest issue is getting the floor clean (not a brand new house) and deciding on a color scheme.
