I didn't want to invest in a coating on my garage floor but I was having issues with salt stains during the winter and needed something to help with that. I used the SX5000 and a week after I applied it I had a gas leak. I cleaned it up really fast but I was surprised that when I cleaned up the gas there weren't any stains on the concrete. If this product works this well after I week and I can't wait to see how it performs in the winter. Very happy so far!
