My frustration is through the roof! After polishing the whole car (again) with Essence and a Blue CCS foam pad, I let it sit for 24hrs then did a very light wipe with Eraser. I sprayed the Eraser on the towel, wiped lightly then wiped over with a dry towel. The original marring has reappeared. With TRC eagle edgeless MF I can press as hard as I want on the paint and wipe, no issue. As soon as I introduce Eraser I get the marring. I've tested directional wiping and the marring is consistent with that.
So, one more time I will polish the car with Essence, no eraser wipe down at all, then apply the dang CQuartz and drive my car again.
I really hope this is a rare experience because I really enjoyed the whole process but this issue has really turned me off it.
