Review on Koch Chemie Weathering Scratches Long Lasting Compression Abrasive & Finishing Products by Maxwell Thomas

I first came across Koch Chemie bars while attending a master class at Apex, one of the best in the US. Since then they have become my first choice. They are similar in sharpness to Rupes medium or Lake Country Orange. However, I think they are better done, polished and finished than nothing else. You can of course use with the appropriate P6 polish, but feel free to try m3, f6 or even other brands like 3D. You will be more than satisfied with the results. The price is a bit higher here in Arizona than anywhere else, but you get top-notch shipping.
