Nice!
Jealous, wish I had the room for a lift.
Agree on the epoxy coating, it's best done to fresh concrete. It's almost impossible to get it to permanently stick to oil-contaminated concrete, even with deep bead blasting and acid etching.
Hot tires parked on the epoxy can cause it to peel. In our shops at work, we tried epoxy coatings and found it better to, instead, clean and polish the concrete and then apply a clear sealer. The finish wore out too but it was easier to refinish. Sure makes cleanup a lot faster.
