Okay, dumb question time - I'm having a blonde moment
I (presumably) understand marring to be a term used for swirls / scratches in the lacquer/paintwork.
I believe micromarring, which I presume to be "light" swirls / scratches, can be caused by using an abrasive polish/compound with something such as a PC or Rotary.
Feel free to correct me on any off the above.
How do you determine the difference between marring, and micromarring when PC'ing a car which had scratches/swirls to begin with ?, ie. how can I tell when the PC has caused micromarring, or if they were already there before ?
If the micromarring was caused by machine, and probably using an abrasive compound, do you simply step to a less abrasive polish and pad combo ?
Sorry to ask soooo many questions, but I just need to get it clear in my head what's what
