I have a 3 month old Mercedes that I have been washing weekly. Here's what i'm using: Meguiars gold class shampoo, S100 polish, S100 wax, chenille wash mitts, and MF towels. I've also just started to use Eagle one QD. I read here (great site, by the way!) that a good way to see how smooth the finish is, and if you need more wax (I have 2 coats of S100 on it) is to put your hand in a plastic baggy and feel the finish. I just washed the car and was kind of disappointed that my hand didn't just fly off the car. It did not seem as slippery as I would have thought. I (gently) used one of my fingers to feel the paint and it kind of feels like there is some very light dust residue on the car. To the eye, the car looks awesome. Are my expectations too high, or did I do something wrong. I'm thinking even though the car was brand new, I should have washed with dawn and clayed. What do you think? thanks.
