My old shop had a full epoxy floor. A working floor, not a show floor. Solid gray, no clear coat. Berrymans B-12 would take most of the tire marks from slicks off the floor but not all. If you can't attack your floor with some really harsh stuff, then Armorpoxy has it.
In an odd note, the floor in the new shop is a KM industrial coating, only part epoxy. Berrymans will hurt it a bit. But no tire marks from any tires, including the big 32x15w donuts on the dragster. Go figure.
