The only place that I know of locally that sells any kind of pads is the Complete Garage out in Lenexa at 87th & lackman, but they only carry the Griot's Garage line of pads. Not bad to use, I use them, but I also use LC and other pads and those I've had to get online. NAPA and some auto paint shops will carry Meguiars & 3M polishes, but I have yet to see pads.
KC Trends, the wheel place, carries Zaino stuff, but I did not see any pads there.
