I use Gold Class on my car, actually I use all Meguiar's products on my car. But for the after wash I used a new product with GREAT Success. It is Dupont Quick Care Detailer. It has Teflon built into it and man it does wonders.
While the car is wet you simply spray over the paint and wipe the water off with either a towerl or chamois. Once you have done the whole car you will notice some places have almost a streak looking thing, like when you get tire wet overspray on the car. Simply take a dry microfiber cloth and wipe the car over good. This works in the Teflon and essentially puts another coat on the car. I started using this over a month ago and what a difference. I used to use Eagle One Wax As U Dry but alls that did was make the paint smooth. This product from DuPont actually rids your car of the swirl marks and other small fine scratches that can develop between washing and waxes. Man I love this product! you can use it wet or dry!
