Hi

you don't want to use any quick detailer if the car is too dusty. You will put light scratches into your paintwork.

If you want an economical quick detailer then go with this, http://www.elitedetailer.com/cgi-bin...mrid=1&cmpid=2 I use this just before I dry a vehicle though, but you can still use it as a normal quick detailer in your case.

But.. If you want something excellent, then go with this:
http://www.elitedetailer.com/cgi-bin...mrid=1&cmpid=2 Its highly concentrated and you will be able to do your whole car with under 10 squirts. It will blow anything from Meguiars into the weeds!
