Yesterday I bought a can of eagle one car shampoo for the first time to see what difference it would make. Just a few ounces in a bucket of water and when i used it i was amazed at its quality. Eagle one claims that after using this shampoo the water does not accumilate as patches when it dries (thus a second round of wiping is not needed). To my disbelief it was true. After using it there were no water patches at all and I'm thorughly satisfied. 9/10 from my end. Anyone willing to spend money on a shampoo i think should give this a try. PS:: I'm not sure if i should spray another round of water over it or not there is nothing specified on the can so for my car i sprayed water. But just to see I washed my bike with the same and didnt wipe, the bike looks classy now.
