I usually use them with D301 Finishing Wax. I've also used them for one stage corrections with M205.
I just used them on a Black GMC Terrain, while using the D300/DMC5, and D301/DMF5 combination. I actually had some d/a haze with this combo. While it could be that I wasn't aggressive enough with the finishing process, I suspect that it was the microfiber being the culprit, so I switched to M66 on black foam finishing pads, which took care of the hazing issue from the cutting step.
I sort of tend to stray away from microfiber for finishing these days, because of the potential hazing. Usually the Yellow Rupes Microfiber finishing pads works great, but it actual l hazed this vehicle too..
