15 The Ultra-Cut compound features super-micro abrasive technology that provides fast cutting and removes 1200-grit or finer sanding marks. Mike set the buffer to 1,500 rpm for this step. He applies the Ultra-Cut on the hood in a straight line parallel to his body. Then he brings the buffer in right to left, holding it at a 10-degree angle; just as he gets to the compound he pulls the trigger to start the buffer. Doing it this way will cut down on the amount of material slung everywhere and wasted. Mike moved in a side-to-side motion with light to moderate pressure. After making a few passes, stop and check the progress—if the paint is shiny, then the speed and pressure you are using is good; if you can still see scratches, then turn up the buffer 100 rpm more and make a few more passes.
