The main reason they advocate straight vs. circular motions is any marring that gets induced will be less noticeable. It has to do with the way light will refract off a straight scratch vs. a circular scratch.BlueBoxer1 said:Pretty cool stuff. Now considering that new synthetic waxes recommend application through a straight-line back and forth motion rather than through a circular pattern as waxes of old, how does the PC fit into that paradigm? The article says it mimics the circular movement of the hand. I thought circular motions were out these days in favor of back and forth motion application?
OK, with that out of the way, your process should be one that does not induce marring no matter what motion you are using. That means only applying product to a clean surface (no dust or dirt), using clean pads, etc.. If I apply something by hand then I will tend to use straight motions, but most of the time I am using a machine (circular) to apply products, and even with a sealant like Zaino I have had very good results.
I feel the PC gives better (more even) coverage and I can apply a thinner coat than doing it by hand. I also feel that waxes and sealants get “worked� into the paint better. One exception that I can think of is Klasse SG which I still apply by hand. Just my 2 cents on the subject. If you have any more questions why don’t you post them in the Machine Polishing forum so this thread doesn’t get too far off topic.
