I just used some stuff called "Hot Traxx" or something like that which I got at lowes. I've driven on it a few times with hot tires (like after driving 15 or so miles at ~55MPH) and it hasn't peeled up yet. I applied just one coat on cleaned, non-etched 50-some year old concrete and let it sit for a week before driving on it. Thus far seems durable.
I think it was like $15 a can or something. I'll take pics of the floor, and the can, tomorrow morning.
