Very pleased with this product.  I used it for sealing my concrete driveway.  I called technical support a couple times.  Eric was very helpful in advising me on best product to purchase as well as application advice.  Granted it has only been several months (time will tell) but thus far I can say it was very easy to apply and so far has sealed the drive well.  This product was considerably more expensive than other sealers I was considering.  It turned out superior to other sealers I've used and glad I made the choice.  I would recommend this product for sealing a concrete drive.
