The crossword solution for the term 'SCRATCHES UP' is MARS, which is an acronym for Micro abrasive Rotary System. This system is used to remove scratches from surfaces such as glass, plastic, and metal. It works by using a rotating head with abrasive material that is applied to the surface to be polished. The abrasive material is then moved in a circular motion to remove the scratches. The process is often used in automotive repair and restoration, as well as in the manufacturing of consumer products.
