Review on Top-Quality Redline Rhynowet Sheets - 220 Grit: Professional Sanding at its Finest by Jay Lee

This is specific to #220 in 9x11 inch arcs. I wasn't sure how this compares to my 3M "gold standard" for wet/dry grinding. In particular, I was concerned about aluminum oxide versus 3M silicon carbide. It turned out that my fears were unfounded. Sheets are more brittle and break easily when folded (or bent) on a sanding block. The scratch pattern left is more noticeable than that of silicon carbide paper - Rhynowet looks "scratchy". If you move through sand before/after #2000, it will come out when washed. Also note: I didn't rate wet performance as my rough sanding is done dry.
