Used this today and wasnt very impressed. A week ago I spent 2 days detailing my car, polishing out all swirls then used blackhole followed by Petes 53 wax. Its rained the last few days so today I decided to wash it. After washing it I used D&D whilst drying the car. It left horrible smears - I have a Blackgold car and it left brownish smears all over it. So after drying it I thought I would use D&D with a plush microfiber cloth, same again smear after smear no matter how much i tried to buff it out.
Its not from using dirty towels or anything as the towels are all brand new and washed once in water as in the instructions. Im going to have to go out and rewax the car now. Smells nice though.
