The best way to beat swirl marks is to never have them in the first place. 3M Perfect-It Random Orbital Compound is a fast-cutting compound that helps you achieve a high-quality finish without the worry of swirl marks or burn through.
3M Perfect-It Random Orbital Compound’s easy clean up formula produces less sling than a rotary system, allowing you to get to the next job faster.
It is part of the easy-to-use 3M Perfect-It Random Orbital Paint Finishing System, which includes pads, liquids, and tools engineered to deliver high-quality finishes for technicians of all skill levels. Available SOP (Standard Operating Procedure) process guides deliver step-by-step instruction for common collision-repair paint finishing jobs.
