you could try an auto parts store. they use the finer grits for color sanding and wet sanding car bodies to make the finish smoother

I find everything up to 2000 grit at my local Pep Boys in the auto body section.

Pat,..if for personal use, try Abralon pads, much better finished product,..and they last a long time. look in www.toolpeddler.com under abrasives,..I only use the 1000-2000-4000, personal preference,..if I want to go lower I use scotch brites....but for finer finishes, these are the best. And they come in the mail...jim
