polishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matte finish leads to considerable
surface damage (shiny, spotted areas).
Always have paintwork repairs performed
at aq ualified specialist workshop, e.g. an
authorized Mercedes-Ben zCenter.
! Do not use wash programs with ahot wax
treatment under any circumstances.
Observe these notes if your vehicle has a
clear matt efinish. This will help you to avoid
damage to the paintwork due to incorrect
treatment.
These notes also apply to light alloy wheels
