Just finished a black Ford GT, and the paint was nightmarishly finicky, so I did some up-front testing. 106FF and Ultrafina with a soft pad, rotary and medium pressure finished down with the ever-slightest halograms, undectible by most people. But when I went to the M205, crazy halograms were left behind...I even played with the 2 medium pressure steps followed by 2 light pressure steps. No bueno. I also tried it via the PC and a soft pad, and heavy hazing (micromarring) was left behing; on dark colors, it's not a final finishing product for me.
I settled on the Ultrafina mixed with 106FA, as the 106FA was really "gripping" the paint like it sometimes does.
