NozeBleedSpeed probably has more experience than I do. But my rule of thumb is that price *does* matter. The cheap microfibers I can buy at discount stores (WalMart, etc.) are generally only suitable for door jambs, wheels, etc. The good MFs (PakShak, Poorboy, MFTech, etc.) are suitable for use on my paint. The only way you'll know the difference if to buy a couple of really good microfibers from some upscale distributors; then, when you feel the cheap ones, you'll just FEEL the difference. :up
