Query: WOW!

Thank you QCI!! I can't afford to refinish my old hardwoods so I thought I'd try this. I had nothing to loose. I needed you to know how pleasantly surprised I am at the results. For this price, the ease of my purchasing experience, quicker than expected delivery and overall results.... I highly recommend this product to others with high traffic makers.. like my kids and dogs... Don't replace... Restore!!
