UPDATE
Well it’s been installed for nearly 6 months now and I still love it.
Ive had some minor edge chips from the small metal wheels of my motorcycle lift when trying to wheel around the bikes. Not a big deal, they’re tiny.
The grout, which allegedly was stain-proof is holding up extremely well. I’ve spilled all types of liquids in it, oils, brake fluid, degreasers and nothing has stained or marked it. It wipes right up.
The metal Reno-ramp is holding up excellent with no issues from cars/ motorcycles/ anything. Other than the typical metal scratches from dragging stuff, it still looks great.
I’ve gotten tons of compliments and it makes the garage look so clean and is extremely easy to clean.
