Comments about Norton Norton SG A975 No-Fil Sanding Discs -- 6 inch:
I have tested most of the velcro-backed sandpapers on the market and this is by far the best. It is a ceramic grit and just lasts forever. I use it for sanding wood - I make wooden bowls for galleries and spend about two hours a day sanding on a regular basis. This is production work, day in and day out. I hate sanding and have gone to great lengths to make it as efficient (yet effective) as possible. The price may seem high at first, but it lasts so long that it is the least expensive paper I can find.
