I have used my PC on about 5 vehicles so far, the lastest being a Yukon Denali this weekend and it took me around 3.5 hours to Polish with #80(Orange Pad) and then top with NXT. I mean this was only a 1 step Polish and it still took me that long. It seems that in order to remove swirls with the PC, you have to move the PC extremely slooooooow, which is why it took me so long to Polish the Denali. Many people on here will say in their thread how long it took them and I don't know how you guys can Polish so fast and still be able to remove swirls, especially when doing a multiple step Polish, like on Black vehicles? I mean it took me the same time to just do a 1 step Polish & Wax that it almost takes for some of you to detail a whole car including Polishing. Any of you have any tips to share on Polishing with the PC and being more efficient (Faster) while still being effective on removing swirls. thanks
