Very little. It is made to work with the step 1 cleaner, which has more of a polishing effect. Megs DC will bring respectable results on a good paint surface that doesn't need major polishing, and it offers a good start point for beginners into the never ending discovery of detailing products. It is also a nice clean, polish and wax product set for those that desire to detail by hand.
There is much, much, much more in store for you in terms of results, however, that can be found in a wide array of other products and methods. As soon as you get a comfort level with the megs, don't hesitate to try out new and different detailing products.
