Switching to a 3-inch backing plate turns a polisher into a precision tool for spots a larger pad can’t reach. It holds small hook-and-loop pads securely, letting you correct mirror caps, A-pillars, door handles and complex bumper shapes. A smaller contact area also concentrates cutting ability on stubborn defects.
- Pair the plate with a pad slightly larger in diameter to protect panel edges
- Check thread size against your polisher before installing
- Clean the hook-and-loop face regularly so pads stay secure
- Run at moderate speeds for better control with small pads
