This is the stuff we have in our garage:
We had the home depot epoxy and that chipped in about 2 months. We've had this stuff in our garage for the past 5 years now and it hasn't chipped at all. We do all of our work on our cars and it has seen its fair share of spills like oil, brake fluid, etc. Still in perfect condition.
Pretty good at taking impacts as well. Changed the tranny in our jeep in the garage, not a single mark left behind from the jacks or the stands.
Rexthane does take some prep work though. You need to go over the floor with the grinder or, preferably, have it shot blasted before application.
Hope that helps.
::EDIT:: Make sure you have a good respirator if you're doing this yourself, the fumes from rexthane are terrible.
