Rupes BigFoot LHR21 Mark III Polisher

The Rupes BigFoot LHR21 Mark III is the largest random orbital polisher in the BigFoot series, built for fast and efficient correction on large flat panel sections like the hood, roof and doors. The 21mm orbit covers significantly more surface per pass than a conventional random orbital machine, letting you remove swirls, scratches and holograms faster without giving up control. Mark III introduces improved ergonomics, an electronic speed dial and a soft trigger start compared to earlier generations. Rupes has built precision tools in Italy since 1947, and that experience shows in the finish and comfort of this machine. This STD version is the bare machine, without pads or polish, ideal if you already have your own accessories or want to expand selectively. For professionals who need to polish large surfaces in a single session, 21mm is the fastest choice in the BigFoot line.

Why this product

• 21mm orbit: fastest correction on large flat panels like the hood, roof and doors

How to use

1. Mount a 6-7" backing plate matching the pad size you're using. (Preferably choose a Rupes backing plate for the best possible fit.)

2. Spread the polish over the pad before switching the machine on. (Four to six drops are usually enough per treated section.)

3. Start at low speed to spread it, then work up to speed 4-6. (Keep the machine flat on the panel and move steadily in passes.)

4. Work in overlapping passes per section and check the result along the way. (Wipe the pad clean regularly to prevent polish residue building up.)

Pair with a Lake Country yellow pad and Menzerna heavy cut compound for fast correction on large panels.
