It was the best experience ever with the Perma shine company. Yes it takes a long time for the treatment of undercoating, but luckily I wwent home to wait. The staff were courteous, the office clean, but the biggest surprise happenned when the manager said" give us a few minutes while we wash your car." I had driven in from the country and the exterior was covered in dirt and pollen. I did not recognize my car when they drove it out to the lot, and the best surprise was the sparkling hub caps.
