Thanks for the responses, Car was near perfect after the coating which was applied with a black pad. I’m going to come to the conclusion about priming the towel wet first then complete a drying process and not start with a dry guzzler.
What did you do before you coated the car?
And it could be that you did not waited long enough to the first wash. It's recommended to wait a week to get the coating fully cured.
How did you buff off the marring after you noticed it?
