I did mine with the Rustoleum kit from Home Depot. $99 for a two car garage. We had a lot of salt and sand this year on our roads and it did a number on the floor, not to mention the plumber that had to dig a hole in the garage floor. Bottom line is I don't think the Rustoleum product is very durable and there is no way to touch it up since its a two step process that hardens after two hours.
I'm looking into the stuff that was advertised in the Carlisle Program and I will now check out the Griots.
The Rustoleum may work in the warmer areas but it doesn't seem to cut the winter traffic here in the mid atlantic.
