Its a black 2001 Audi. In the past I would only wash and wax. But from reading the forums i realize that some kind of polish needs to be used...so i picked up #7. Not sure if thats the right one for my car, but i hope so..it says clearcoat safe. #7 got rid of cob webbing that I'd see in the bright sun, but IS it too abrasive for the age of my car? I think my paint is in pretty alright condition for a 3yr old car. My paint doesnt feel glass smooth so I read that a claybar will help that...will pick one up this weekend. Finally, I notice some streaking in the bright sunlight when I use the Quik Detailer. So if you guys could prescribe the right products for my car...i'd appreciate it.
