Basically, you want to use the softest foam pad from the brand you choose. Put the PC on about 3.5-4 you don't need more. Make sure the pad is clean and dry and the wax has already turned to a haze. Sometimes I keep a bottle of water (but the quick detail sprays also work good) with me just in case there is an area of thicker wax and its not being removed. I just give a little squirt to get it moving again and then keep moving so the pad dries. This will basically melt the wax into the finish better, creating a better bond, and also a much higher shine than I think you can get by hand. Most important note about this method is that using a MF towel by hand I feel can put in scratches because, (A) its no always a brand new towel and may have some leftover junk in it. (B) you are pushing with your and and fingers at different pressures on different parts of the car and depending on the condition and nap on the towel you could push hard enough to scratch. (c)In order to use a MF towel properly by hand you must fold it at least twice into four sections to have enough cushion so you don't put your hand or finger pressure into the paint. With the soft foam pad you never have to worry about this because the foam always is cushioning and gives. It will contour and flex around the shapes of the car and never put direct pressure. This is just my opinion that I shared with Justin. It is the way I do cars and recommend doing them. Added plus is that it is much easier to use the PC to remove wax than it is by arm and shoulder pressure and in my opinion also safer on the paint. I use the MF after I am done to just lightly dust the car and get the wax out of the cracks of the hood and doors and trunk areas. Just my two cents!
