As many of you members know I can't keep from detailing. So I ordered Autoderm and it's QD. My car has about 10 coats of Pin. Souveran on it. So I wondered what would happen. Applied with MF applicator. A small amount is all it takes. Spray a little QD on App. w/ AD. It applies nicely (do entire car). Let it sit about 30 minutes then wipe off. No dust or anything. It definately added some gloss and depth to the already PSouveran. I ready like its looks. Added a second coat 24 hours later. Very imipressed with the product and the QD. Durability I don't know. My red metaflake sparkles great. Looks are my no.1 priority and Aquaderm fit it well. AutoDerm Rehydrating Car Wax, Car Polish, Car Care, Auto Care, Carnauba Wax, Car Detailer JMHO
