Aw man...Though I do get up on my High Horse and lecture about (micro?)marring like it`s the end of the world, I honestly don`t want people to go looking for problems...minor cosmetic problems...that they don`t know they have! IT DOESN`T MATTER unless you think it does!
Will other people judge you based on such stuff (or your diction, or appearance, or....something...)? Sure, of course they will! Somebody`ll judge everybody for something every minute of the day. Do you care? That`s your business. OK, that said...
If you`re using mild clay, the clay itself shouldn`t mar, period. The marring comes from either using that clay incorrectly (e.g., insufficient lube, excessive pressure), or from abrasive contamination that`s stuck in the clay.
The instant the clay picks up a speck of something abrasive, it turns into potential sandpaper. That`s why I`d never use a machine-driven system as there`s no way to stop and knead/clean/replace the clay after every momentary contact with the paint (if that`s necessary) and thus avoid marring. Yeah, that`s a huge PIA...which is a big reason why I advocate chemical decon instead of mechanical.

It`s not the pad, or even the dirt...., it`s the speed of using the machine... it`s WAY TOO FAST!
Uh-oh, you lost me there...how would the speed be the determining factor? It`s not moving fast enough for heat to be an issue, and other than abrasion and heat I can`t see a cause for marring (i.e., if heat isn`t an issue, the speed with which you move the decon media in-and-of itself wouldn`t factor in at all... unless I`m missing something).
