I did Ucoatit. about $900 for a 3.5 car garage though, so a little pricey. The only part that has peeled is lip outside of the garge. just the clearcoat though, the base coat is permanent. You put mix the first layer of base coat extremely thin, almost a watery consistency and it permeates into the concrete, then you do one more color coat, throw the flakes on while its wet and then a couple coats of clear urethane. Best product I have ever used. It has been down 8 years now.
for some reason the pic won't show. its been on imageshack for a while now, maybe it will come back
