I was a house painter for forty years. That means I worked with sandpaper almost every day. So I'm well aware of what abrasives can do. When I got back to riding after a thirty two year hiatus I went back to the t-shirt deal. However I just couldn't get comfortable with all of that abrasive zooming by underneath me at speed. So after the first year back I became an atgatt guy with a closet full of all the top name gear.
