Do you rotate out the pads during the process? I typically use 3 or 4 pads when doing a job. When one pad starts to warm up I'll pull it for another fresh one. Are you priming the pad or applying the polish to the surface?Seems like whatever pads I use on my Griot's Boss 21mm don't last very long either. The paint surface doesn't get too hot with an orbital but the pads sure do!
