Hard to imagine that it wouldn't hold up. I think it could work but I would be curious if oil leaks or other contaminants would have the possibility of dissolving the resins in the flake board. If you had a good 2-part epoxy to coat it when done you might have a pretty nice floor.
This is what I put on mine 4 years ago and it is holding up pretty good.
