Protection and polishing
Protection
A hard wax treatment protects the vehicle paint.
Repeat the protective treatment by applying a good hard wax product at the latest when water no longer beads on the clean vehicle paint.
Even if you regularly use a protective product added to the water of the car wash, we recommend treating the paint with hard wax at least twice a year.
Insect residue that adheres, especially in summer, to the front of the bonnet and the front bumper is, moreover, much easier to remove if the paint has recently been treated.
Polishing
Polishing is only necessary when the paint has dulled and the use of protective product no longer restores the desired shine.
If the polish does not contain protective ingredients, the paint must then be treated with wax.
Warning!
Matt painted parts and plastic parts must not be treated with polishing products or hard wax.
