Uneven movement (tilting) of the polishing machine's lambskin polishing disk may cause so-called "buffer swirls" during polishing.

Such marks may degrade the vehicle's overall appearance since they become visible on the paintwork as semicircular streaks (arrow) if (and only if) painted surfaces are exposed to direct sunlight or round-shaped artificial light sources.

Clear buffer swirls 

  1. Thoroughly wash and dry all affected areas or parts. Remove any paintwork contamination with the appropriate MB cleaning agent (e.g. tar remover, insect remover).

    IMPORTANT Please note processing specifications on the respective material containers, since failure to use the materials properly may lead to inadequate results.

  2. Mask all non-painted detachable body parts made of plastic (e.g. door handles) as polishing agent residues cannot always be completely removed from such parts and may leave bright stains.
  3. Polish the entire part using a variable-speed polishing machine with a Moltopren disk and fine polishing paste.

    IMPORTANT

    • Move the polishing machine across the areas to be polished applying light pressure (the polishing machine's own weight is sufficient); be sure not to tilt the machine.
    • Remove any polishing residues with a wet sponge and wipe the surface dry.
    • Only use fine polishing paste on severely scratched paintwork surfaces.

    NOTES Generally we recommend not using a lambskin polishing disk since polishing operations with such disks may cause "buffer swirls" even if no polishing agent is used.

  4. Replace the Moltopren disk that is soiled with fine polishing paste with a new one and then re-polish the entire area mechanically until the required luster is achieved.

    IMPORTANT Use a separate Moltopren disk for each polishing agent (fine polishing paste, polish) to achieve a satisfying polishing result.

  5. Clean the polished surface with a damp polishing cloth. A bright, milky coating will develop on the paintwork after a short drying period (5 to 15 minutes, depending on weather conditions). Rub off this coating with a clean, woven or non-woven polishing cloth until the paintwork is clear and bright.
  6. Manually re-polish the polished area in a longitudinal direction (no circular movements) using polish and a dense polishing sponge. Polish residue can be removed with a damp polishing cloth. After a short drying period, the milky coating can be rubbed off with a clean, woven or non-woven polishing cloth until the paintwork is clear and bright.
  7. Apply a thin, uniform coat of gloss preserver to the previously polished surface to preserve the shiny luster and protect the paint from premature weathering.

    IMPORTANT Use a clean non-woven polishing cloth to rub off the gloss preserver once it has dried (white film). Rub until the paintwork is clear and bright.

    IMPORTANT

    • Do not polish surfaces in direct sunlight or while they are still warm (e.g. engine hood).
    • Shake polish and gloss preserver containers vigorously before use.
    • Frequently replace non-woven polishing cloth with new one to facilitate polishing and obtain optimum results (e.g. replace polishing cloth 4 to 5 times for polishing an engine hood).
