Epoxy on your garage floor.

[Goodspeed]

Pretty good on my end. The clear top coat we put on had some areas that turned white-ish after drying - kind of a spider web effect. If memory serves it appeared when the temps dropped (coated in the fall). A few small spots here and there (and a random large one in a low-traffic area) have lifted, but I had some matched floor paint mixed up and the touched up areas have been doing well.
