I have epoxied my grage floors. It adheres well to wood too. I had wood step leading from garage into house. Don't get the cheap stuff you find at home depot or lowes if you plan to do the garage floor, as it will peel up from hot tires.

I would suggest maybe using treated lumber that touches the grage floor as mentioned.
You also could put some flat aluminum stock between the floor and wood as well. That will hold up very well too
