“This product is very easy to use. The shine is very nice considering how easy it is to apply. Our cars look great as long as they don't get wet. The protection lasts about 1 to 2 months at most if your car see rain. If no rain, the shine will last 6 months or so. If washing your car you must use their ceramic car wash. If you don't, the wash has the same affect as rain. There are pluses and minuses. My final thought is that for what this product is, it is too expensive.”
