I just saw a show on Speed or something that highlighted a new MFG of garage floor coatings -- Rock Solid Floors (
RockSolid Floors Polyurea Garage Floor Coating). Their product is Polyurea based (same ingredient in truck bed liners) instead of epoxy. It is supposedly a lot more durable and easier to work with than epoxy based products. A little on the expensive side but may be worth it if it lasts that much longer than epoxy.
