I like some had heard all the storys about how good your products are until I finally gave in and purchased a quart on the gas additive and my mileage increaced by 3 miles more per gallon now I use it in both of my trucks and my boat. I just bought a bottle of the slick mist MAN does it ever do wonders for making the paint sparkle, I tried it on aspot on my old 1990 truck and ask my wife if she could see where I had used it, you guessed it I ended up doing the hole truck. My next test is on my boat. THANK FOR A GREAT PRODUCT!
