I used this product to polish my crankshaft bearing and seal surfaces in my car. It does the job but I don,t think the grit surface lasted as long as some American crocus cloth that I used in the past but it is cheaper.
Being an artist of many years, I discovered this surface to be a fun sub-strate for my wax pencil drawings. It yields an "old world" look to my drawings. Love the crocus cloth sandpaper.
