I'm detailing my car now, and getting pretty good results from M205! I only have a 6" DA, so I'm getting the shadowline by hand...exhausting but worth it so far! I clayed the trim first with an Eagle One Clay Mitt and now using the M205! Pictures will come later!
EDIT: These were some quick Before/After's there was maybe 30 seconds between pictures, so it doesn't take long. Obviously more time will give you better results! I was just doing it quick for the sake of pictures!
