Vehicles with dull clear varnish exhibit a significantly reduced degree of luster. The regal-looking matt effect is created by flatting agents in the clearcoat. The flatting agent in the clear varnish produces an uneven surface, thereby causing - in contrast to bright clear varnishes - diffuse light reflections, which result in the "matt effect". MAGNO paints can only be ordered through the designo individualization offer. SHAPE paints are also matt paints, which - in contrast to MAGNO paints - are available as series colors.
Paint repair
In close cooperation with the Mercedes-Benz paint partners (SI98.00-P-0002A ) repair solutions have been developed for all the paint systems. The repair procedure corresponds to a conventional paint finish with the exception of the clear varnish system that is to be used.
The following special considerations should be observed:
Before starting order preparation, additional work such as, e.g. removal of engine hoods, tank filler recess or doors must be taken into consideration and coordinated with the customer
Paint repair
In the case of a repair, both the color and the luster of the vehicle must be determined. Therefore, before starting the repair, a sample panel should be made first with a base coat and a dull clear varnish. It may be necessary. to produce several sample panels until the color and luster match the vehicle involved.
The luster can also be measured using a reflectometer. For matt paint finishes, it is 23_E (±7) when measured at a 60° angle.
When producing the sample panel care must be taken to ensure that all the application parameters are selected in such a manner that they can be used later on for the paint finish. Different application parameters during creation of the sample panel and subsequent painting may have a negative impact on the cohesion of the color, luster, etc.
Painting the parts "edge to edge" is recommended. If this is not possible, we recommend a large repair of the entire damaged side of the vehicle. Furthermore, spot repairs and touch-ups on parts are not recommended.

Care and cleaning
Maintenance
A matt finish requires special care to ensure that the dull surface is retained. The use of paint cleaners, grinding and polishing products such as gloss preservers (wax) on matt finishes must be avoided at all times.
A vehicle with a matt finish must never be polished.
This results in severe damage to the matt surface in the form of high-gloss, spotted areas. If polishing is performed, the matt effect can only be restored by painting again.
Excessive rubbing with unsuitable products can cause the matt effect to brighten.
After any rubbing with unsuitable products the matt effect can only be restored by renewed painting.
Cleaning
The following rules must be complied with for the correct care of matt clear varnishes:
- When cleaning manually, a soft sponge, shampoo (matt-coat care set) and a lot of water should be used. Always avoid washing in direct sunlight.
- Frequent use of washing facilities can increase the level of gloss thereby reducing the matt effect.
- Any stuck insects, bird lime, resinous, grease and oily substances, as well as splashes of tar and tar spots must be removed immediately. We recommend soaking in water and using the matt finish care set.
- Avoid sticking any adhesive labels, films, magnetic signs or such like to the paint surface, as the adhesive residue could damage the paint.
- An approved metal dust remover can be used to remove metal/industrial dust. It should be ensured here that the metal dust remover is used on a thoroughly-cleaned surface, and that the surface is then throughly cleaned with clean water. On no account should metal dust remover be used several times in succession.

A matt finish care set is available for the care and cleaning of matt surfaces, which has been specifically checked in terms of material compatibility.
