It's an excellent detail spray / waterless wash product that smells nice too! I own a Corvette and I'm obsessive about the finish on my car. I have the McKees ceramic coating on my car and I use this as needed to keep my car looking great! Spray on, wipe off and everything is gone! Tree sap, rain drop residue all just wipe away.
Pros:No streaks! Everything just wipes away. You only need a light mist of product to keep your car looking good.
Cons:The only negative is that I don't get it for free! But the fact that I willingly buy it in a gallon refill size should speak for itself.
