I just tried the system one x3 and no it dosent compare to the power of the m105 but i will say it did a pretty good job.My car wasnt really to bad but it def needed a polish so i tried system 1 with their pad setup.
The polish worked good enough but the wool pads just dont cut it as they wear and just flatten out to fast.I also wasnt thrilled with the finishing side as i had to just stop using it and went with menzerna po85rd to bring the gloss back.
