Mike - is that due to dusting from 105? I agree Griots does not dust like M105 but if mixed with some 205, that does help a bit. Never tried M100 or 101.

M105 will only dust if you work it too long without adding a spritz of something.. Most compounds, probably all compounds, etc., will dust if run until they dry up..

That`s why I have always made sure to keep M105 moist enough to get passed its initial, dry up spell, and then it keeps working and working until you finish it down beautifully..
Heck I even used M105 and M205 with Lake Country Purple Foam Wool and then L/C White foam pads on several BMW Jet Black and Lexus Jet Black vehicles with very damaged paint and got this paintwork incredibly clear, glossy and flat..
I`m glad Mike found a product that he likes so much more than the Meguiar`s products, but they are still working great for a lot of people.
At a very Auto Detailer-focused Sherwin-Williams Automotive Paint Store in Bellevue, WA., I always had a hard time purchasing M105, and one day I asked them, "why are you always out of it??" And they replied, "we sell the heck out of Meguiars M105 to people that build Fire Trucks and Ambulances, they use it to finish these vehicles after they paint them, we can barely keep up with their supply alone"..
Oh, one more thing, these people ( and of course, yours truly), all use Rotary Power..
