I did mine with the Epoxymaster 100% solids kit from Costco about 4 or 5 years ago and it's still solid. Surface prep, 100% solids and application are all important. For example, you shouldn't install when the humidity is high, things like that.
I would spend a bit more to get 100% solids. This one at Costco isn't the one I used but looks solid:

Get a pair of spiked shoes as well as you cannot walk on it at all once you're done. You will probably want everything laid out and measured and ready to go, you have VERY limited time once you start mixing, and that only gets worse on a warm day, so select well. If i was doing a 2 car garage i would definitely do it in 2 sections unless you have like 4 people helping.
