Can be purchased at Target for $5.99 a bottle. Has a small amount of carnauba. Spray on, buff off the fine haze w/ MF. Restores the just-waxed look in minutes without having to completely rewax. The only other one I have tried is Mothers and that just seemed like spraying water on my car to me. Didn't seem to really add anything. Is there a downside to using a QD with wax in it?:nixweiss
