ishing products, or glos spreserver, e.g.
wax .These product sare onl ysuitable for
high-glos ssurfaces. Thei ruse on vehicles
wit hm att finish leads to considerable sur-
face damage (shiny, spotted areas).
Always have paintwork repairs performed
at aq ualified specialist workshop, e.g. a
Mercedes-Ben zService Centre.
! Do not use wash programs with ahot wax
treatmen tunder any circumstances.
