*badbadtz.carlo: I have the same take as Jon's, but based on experience its really a very versatile product, so when you apply it by hand try not to apply too much pressure and check the results and based on that, thats how you should determine how to tackle the whole car. See with just moderate pressure i can already remove moderate swirls, and with firm pressure and some more passes i could even go as far as tackle some severe defects already, so the pressure it applying the product is one main factor that is why i would recommend you use it starting with light pressure first. But when used with light pressure, lets say working the product for a good 3 to 5 minutes per big panel with the same pressure just like massaging/spreading the wax, i could already remove a lot of defects already. Also be sure to work the products and break down the product completely, because if you don't work it completely until its clear you might end up with a slightly hazed finish. Thats about the 2 most important tips i can give you but overall its a great product.
