I have never seen the point of garage floors. Some people seal them or Racetrack. Forget that. I use mine. Poured the slab, garage went up. Smooth finish. I sweep it. I weld in there. I work on my cars. Oil spills just get some kitty litter and scrubbed. It is a work garage, not a dang showroom for eating off of. I do not keep my vehicles parked in there in winter. Garages are for guys, cars are for car ports
Look at ghostshield products. One of the vendors here carries it. I used the 4500 densifier and have the 8505 sealer to put on in a week. The 8505 is approved for Dot bus garages so I figured should last a long time in my shop. Neither product makes the floor slippery and is transparent. The 8505 resist oil, antifreeze, and salt damage.
