?I agree Mark.? I'm a retired physician.? Did you know that 10% of "controlled studies" are reproducible in follow-up studies?
At least this sandpaper study represents an attempt to sort the various brands.? When I first started woodworking, I assumed "sandpaper is sandpaper" and bought cheap junk.? I quickly discovered that sandpaper is NOT just sandpaper, and some kinds are far more useful than others.? Mirka abranet mesh has been my go-to for the past 2 years--it works quicker, lasts longer, and leaves a better finish than other brands I've tried from HF garbage to premium stuff and makes sanding if not a pleasure, far less of a chore.? Based on this study I've ordered some Xtract cubitron in various grits to try--worst case, I'll go back to what I've been using.? Best case,? I'll have found a new, considerably cheaper, solution.? ? Without the study, I'd never even have looked elsewhere.? Jeff
