Regardless of how clean you think your paint is, there are still contaminants stuck on the paint that you need to remove before waxing or polishing your paint. Paint Cleaning Clay leaves behind an ultra-smooth surface that will make your wax adhere better and last longer. It also makes the wax much easier to buff out. Paint Cleaning Clay is safe for all paint and also works great on glass to get it squeaky clean. Paint Cleaning Clay requires Speed Shine to be used as a lubricant for proper application. Simply spray your paint surface & slide the clay across the paint. No need to rub hard. Wipe dry & your finish is like a baby's butt without the streaks. Follow up with our paint sealants or waxes. You owe it to yourself to try Paint Cleaning Clay and Speed Shine!!!
