Hey guys!
Presta was really designed for the rotory with wool, but will still get real good results using a pc and foam pads. It all really depends on the paint, color, make, and age. Considering it is a MB with hard paint, a rotory will do the job the best at removing the scratches and bringing the gloss to the max. Whether you use a foam cutting or a wool is pretty much preference. I prefer wool because it deep cleans, corrects, and brings out a true clean glossy finish with ease with proper speed. After that use a foam polish or finish pad on the rotory or pc with a finish polish and the rotory/wool swirls with dissapear with ease while leaving a very bright, glossy and vibrant finish that is 100% swirl free. Being a beginner is the only tough part on learning and correcting while leaving a flawless finish. I should make a DVD someday and sell it.
Hope this helps.
