Our opinion:
SCHOLL Concepts S20 Black is a relatively recent addition to the SCHOLL Concepts line of compounds and polishes and, like its ancestors, uses the same one-step abrasive technology to great effect, albeit with the addition of a neat trick. ; Extra cut and extra shine. These two parameters are usually mutually exclusive, but through further development of their smart powder technology (iPT), SCHOLL Concepts have made the impossible possible. SCHOLL Concepts S20 Black cuts like an aggressive cutting compound, but finishes like an ultra-fine finishing polish; As long as you select the right speck for the job, you will always produce a product-ready finish from the last step in a single polishing step (you may still need to do multiple sets on some panels, but you'll never have to go back to a refining process multi-stage). This makes it, by some margin, the best one-step compound on the market right now. You can use in any color!!!

Description:
SCHOLL Concepts S20 Black is a one-step, high-performance cutting compound designed to cover a wide range of correction tasks in all common paint systems, including modern nano-ceramic and scratch-resistant clear coats, and conventional paint finishes. SCHOLL Concepts S20 Black uses cutting-edge, high-purity aluminum oxide Intelligent Powder Technology (iPT) abrasives that break down quickly with use, forming a progressively finer polishing residue. As a result, the level of cutting it offers quickly decreases from a moderate strength cutting compound to an ultra-fine finishing polish, meaning it corrects and refines the finish in a single step. By choosing a suitable pad for the type of paint in question, the overall level of cut can be carefully controlled, meaning perfect results can be achieved every time. To further help, SCHOLL Concepts S20 Black introduces new easy-clean lubricants that optimize efficiency and make polishing easier, while its filler-free formula ensures defect removal is permanent rather than temporary.
