This 32oz concentrate mixes at 3:1 (water:detailer) to give you an entire gallon of Optimum Instant Detailer & Gloss Enhancer - at $19.99, this is an outstanding value. We've found this detail spray to be one of the slickest and most user friendly detail sprays on the market today. Use it at car shows or after a weekend cruise to clean light dust from your vehicle, enhance the shine and slickness of your finish after wash, or take your wax or sealant to another level after a full detail. This detailer is extremely versatile and also works very well as a clay lubricant. Like Teflon, Optimum Instant Detailer utilizes fluoropolymer technology - you'll be amazed at the slickness and lubricity this product provides for your vehicle's finish. One reason we chose to carry the 32oz concentrate instead of the 17oz pre-mixed bottle is to provide a better value to the end-user. And after trying it once, you'll be glad you have an entire gallon's worth of product!
