i'm not a pro detailer and do it just as an hobby,
I did more than a few card but never a Mercedes with their Ceramic coat.
this car was washed in the "swirl machines" - automatic car washes... and was in a very poor condition.
I tested - Meg's D300 with MF pad, it just took out the swirls and left a whole lot of RIDS.
then tried Menzerna SF1500 with Meg's MF pad and still left with RIDS.
Stepped up to M105 with MF pad and had to do 3~5 section passes to get ~70% of the RIDS cleared up.
here's a short video of before and after
