I've been using both Meguiars #9 swirl remover and Griots Garage Machine Polish #3 with a PC 7424 and Griots orange foam polishing pad on my wifes black ML350. Although I work in the products until nearly dry, as both manufacturers recommend, I still find it difficult to remove. I usually wind up spending an exessive amount of time removing the haze that always seems to linger. I use both cotton towels and MF towels. Although the MF towels do a better job at removing the haze, I still think that it's taking longer than it should. I sometimes spray some QD on the vehicle which also helps. Does anyone have any application or removal tips that may help?
