I have a large shop for work. This garage is for the daily drivers, the wifes car may go in and out several times a day bring in dirt, rain, etc. This garage serves as an entrance to our house that most people use so I want something nice. The epoxy has worn off in the tire tracks and around the center drain. Before I thought of the rubber coin I was looking at the Race Deck Free Flow, this would let the water fall threw and get to the drain and the a couple times a year I would shop vac it to get most of the dirt out. The product you have is what I'm looking at and I would cover entire floor and may glue it down.
