Maintenance and Warranty Guide.
Matt finish
If your vehicle is coated with a clear, matt
varnish, it is essential that you take the
following instructions into account to avoid
damaging the paint, due to an inappropriate
treatment. These instructions are also valid for
the alloy wheels coated in a clear, matt varnish.
Textured paint
The textured paint reacts to light with variations
of appearance and finish that emphasise the
car's lines and form. This paint coating has
particles that remain visible and create a
unique satin relief effect. Its lightly granulated
texture gives it a surprising feel.
