I don't think there is a manual process that will eliminate swirl marks, in my experience.

not sure why you asking for a product that does not require a PC, but I would find a way to get one. with a PC, there quite a few products that do a fabulous job, and you can mix and match different removers with different types of pads to get just the look you want.

As for car shampoo, I use Pinnacle's body shampoo. Great stuff. It feels really really slick when washing which is a good thing!
