I have had race deck in my garage for well over a year now and am completely happy with it. I used the red and graphite colors as we have red dirt here that really shows on white. So far I have dropped a car on a jack stand on it with sharp edges and it made a very small nick. I have ran the washing machine over and had an area of about 8 square feet of water and suds. I have tracked in snow and water from rain as well as mud. All cleaned up easily. After a few days I lifted the tiles where the washing machine ran over and took a small towell and wiped up what little moisture was left. I also ordered a few extra tiles of each color so I replaced the one that I knicked with the jack stand. I have walked on it in just my socks and every shoe that I own both wet and dry and have yet to slip. For me that is saying something as I can fall down just waking across my living room. I used a table saw to trim the edges and could have done a better job but was in a hurry at that point. Most of them are out of sight under the cabinets anyway. My steel wheeled floor jack has not left a mark and I have drug it all over the garage.
Edit: If you are worried about jack stands, do what I did. I took some old carpet that I had, cut 8 patches about 4" square each and used E-6000 glue. I put the glu on the edges of the jack stand bottoms, put them on the carpet pieces and they have lasted years. I did this while I had a painted floor and they were gouging it up. As for the steel wheels on the floor jack, I went to the hardware store and bought a roll of velcro. I just took the smooth side and cut strips that were the right length and put two on each wheel. Really quited the noise when I drag the jack and has lasted for a couple of years now.
