foils are impaired by:
- Sunlight
- Temp erature (e.g. hot air blo wer) -
Weather conditions
- Stone chippings and dirt
- Chemical cleaning agents
- Oily products
R Do not use polish on matt decorative foil. Po l-

wrapped sur face.
R Do not treat matt or st ructured decorative
fo ils with wax.Pe rm anent stains may occur.
Scratches, cor rosive deposits, areas a.ected by
cor rosion and damage caused byincor rect care
cannot alw ays be comple tely rep aired. In this
case, contact a quali/ed specialist workshop.
Yo u can obtain more information on care and
