Polishers
Choosing a Polisher: Rotary, Random Orbital, or Dual Action
Polishers remove swirls, oxidation, and scratches from paint, gelcoat, and stone, then bring the surface to gloss. Cordless options include Milwaukee M18 FUEL random orbital polishers in 15mm and 21mm throws, the M18 7" rotary, DeWALT 20V MAX XR 5" random orbit and 7" rotary models, and Makita 18V LXT, 40V max XGT, and sub-compact 3" units. Corded picks include the Makita 9227C and 9237CX3, RUPES BigFoot LHR15 and LHR21 kits, the Festool Shinex RAP 150, and Porter Cable 7424XP.
What to Look For
- Action. Rotary polishers cut fastest but take skill. Random orbital and dual action polishers are more forgiving for paint correction.
- Throw size. A 15mm throw suits smaller panels and curves. A 21mm throw covers large flat panels faster.
- Pad size. 3" polishers handle spot repair and tight areas, 5" and 6" are all-round sizes, and 7" rotaries cover big surfaces.
- Specialty use. The Makita PW5001C is built for stone, and Milwaukee M12 FUEL tire buffers prep rubber for tire repair.

Polishers FAQ
Should a beginner start with a rotary or random orbital polisher?
Start with a random orbital or dual action polisher. The pad oscillates as it spins, which spreads heat and makes it hard to burn through paint. Move to a rotary once you need faster cutting on heavy defects.
Do I need a different pad for each step?
Yes. Use firmer foam, wool, or microfiber pads with cutting compound, then a softer pad with finishing polish. Keep pads separate by step so heavy compound does not carry into the final pass. See polishing supplies.
