3.1. Step 1: apply polish

The polish is always applied in the same way:

  1. Put a blob of polish directly on the paintwork or in the lint-free rag and rub the car evenly. This creates a milky layer that must not be too thick, but must be even. Be careful not to rub plastic parts, headlights and windows. Otherwise these have to be cleaned again afterwards and may be attacked.

Wear the Polish on the polishing hood and moisten it with a little water from the spray bottle. In this way, the agent is distributed more evenly on the paint. Then run the machine at medium speed in circular movements over the entire paint surface.

Make sure that the polishing sponge of the device is always sufficiently polish and moist so that the paint is adequately cooled. This will gradually polish the whole car, the last step is to polish by hand all the places on the car that were inaccessible by the machine.

Danger: You should only apply light pressure with the polishing machine on edges and corners.

To repolish, pull on a fresh polishing hood and finally bring the paint to a high gloss. Just press lightly. When you have removed all the polish residue, your car will shine again in a new shine.
