1. Quality refinishing

The term “quality refinishing” is used in general to refer to a perfectly executed repair of damage which may have been caused in an accident. The aim of this is to ensure that as far as possible the client (e.g. the vehicle owner) detects no visual differences from the OEM coating or the area surrounding the refinished vehicle panels (colour match, gloss, appearance etc.).

1.1 Preparation for spraying

Carrying out a quality refinishing job as described above is dependent not just on the spray painter’s expert skills, but also on the observance of the prerequisites set out below:

o Scrupulous cleanliness (all around the bodywork to be sprayed)o Selection of suitable tools and equipment (sanding media, sanding equipment, masking

materials and tapes, cleaning cloths etc.)o Selection and use of the necessary degreasing and cleansing agentso Selection of the appropriate refinish materials for the respective purpose and their expert

application in accordance with the paint manufacturer’s Technical Information andrecommended processing method

o Selection and expert use of the relevant polishing media and equipment, polishing cloths etc.for finishing the repair areas and neighbouring car body surfaces.

In addition, of course, modern workshop equipment, a well organised workflow and workplace and, naturally, also the spray painter being trained in the latest techniques play a significant role in achieving a quality refinish result (“first run OK”).

Remarks: All work must, of course, be carried out in compliance with the applicable health and safety provisions, e.g. gloves, respiratory protective equipment. protective glasses etc. (personal protective equipment) must be worn.

o It is also mandatory for the relevant environmental provisions to be met.o The “mixed use” of paint from different paint manufacturers is not permitted, for both quality

and warranty-related reasons!



1.2 Sanding process

The sanding media industry now offers outstanding, highly efficient sanding media tailored specifically to every sanding process and every refinishing technology. Today’s modern refinish products are now all (from the undercoat material to the topcoat) designed for dry sanding. Accordingly, the sanding process which may be necessary is substantially more efficient than wet sanding, while retaining an optimum sanding result.

As already described in 1.1, the selection of the most suitable sanding media and equipment (e.g. grit, random orbital sander) is especially important both for the refinishing process and for the respective refinish paint. It is essential to follow the specifications and recommendations of the refinish paint manufacturer in order to achieve the desired high-quality coating result with the greatest possible quality and efficiency. Please refer to the relevant technical information for the correspondingly detailed information and recommendations.

In addition, the respective recommendation of the sanding media manufacturer (grit, waiting time, equipment, orbit diameter etc.) is also very helpful in achieving an efficient operation.

Remarks: The sanding equipment to be used must always be appropriately connected to a dust extraction system. Regular maintenance and cleaning are absolutely essential to ensure the maximum suction performance of the dust extraction system.

A very wide range of materials (aluminium, magnesium, plastics, carbon fibre etc.) is used nowadays in the modern automotive industry, including for the outer skin to be sprayed, in order to save weight, among other reasons. Particular attention must be paid to this development because serious problems in terms of quality and personal protection can occur during any sanding operations which may be necessary (see below).

Aluminium o Risk of galvanic corrosion as a result of the simultaneous use of a sanding medium for

aluminium and sheet steel/galvanised sheet steel o Risk of a dust explosion in the event of an inadequate dust extraction system or the complete absence of such a system

Recommended measures o A separate workplace must be created for working on aluminium surfaces, and this must be

used exclusively for working on aluminium substrates. o All products and equipment (e.g. sanding media and machines) must be used exclusively in this area (aluminium workplace). o An effective dust extraction system for the aluminium sanding fines is absolutely essential.

Here, too, regular maintenance and cleaning of the dust extraction system are absolutely vital.



Carbon fibre reinforced plastics (CRP) o A dust explosion can occur when sanding carbon fibre surfaces in the event of an

inadequate dust extraction system or the complete absence of such a system (see alsoAluminium).

o When working on visible carbon fibre surfaces (as in the AMG GT, for example) the paint manufacturer’s technical data sheets must be followed in order to ensure that the right sanding medium is selected.

Recommended measures o A separate workplace must also be created for working on carbon fibre surfaces, and this must be used exclusively for working on carbon fibre surfaces. o All products and equipment (e.g. sanding media and machines) must only be used in this

area (carbon fibre workplace).o An effective dust extraction system for the carbon fibre sanding fines is absolutely essential.



1.3 Primer fillers for warranty repairs

If a warranty repair has to be carried out, this is usually a repair in which, for example, undercoats with the maximum possible corrosion resistance are used. The aim of this is to achieve a level of corrosion protection which is largely comparable to that of the OEM coating.

Two different technologies can be used for this very demanding quality requirement which differ primarily in terms of the binder chemistry used:

1. Epoxy Primer Filler (801-72 VOC)- Traditionally widely used product with varied usage options- Good corrosion protection- Can be used on steel, galvanised steel and aluminium

2. PU Primer Filler Pro (285-270)- Latest undercoat technology- Very good corrosion protection- Varied options for use (e.g. adhesion promoter, corrosion protection, wet-on-wet processing,

greyshade filler etc.) - Can be used on steel, galvanised steel and aluminium

Please refer to the following pages for detailed information relating to use and the refinish system.

4.2 Tri-coat paint systems (example: hyacinth red MB 3996)

The Mercedes-Benz hyacinth red colour is a translucent tri-coat paint system. It is not generally necessary to paint adjoining body panels. If colour deviations which exceed tolerances are to be expected, however, it can be more expedient to balance these out by blending them to fade. The spray painter has the choice here, depending on the actual damage, of spraying only within the panel or fading into the adjacent panel. This method can be substantially more efficient and cost-effective than time-intensive retinting.

Various basecoat steps are used for the method shown below:

- Step 1 basecoat providing colour and effect (base colour) - Step 2 translucent basecoat - Mixture of step 1 and step 2

4.3 Matt finish

Refinishing process for 90 Line basecoat/clearcoat systems with Glasurit 923-55 MS Clear extra mat and Glasurit 923-57 MS Clear mat elastified.

Due to the different mixing ratio ratios of the clears to be used, you may achieve a gloss level between12-65 units (at an angle of 60°). The gloss level may be higher for light and pure silver colours.Additionally, car bodies may show gloss level differences between vertically and horizontally coatedpanels. Therefore, we recommend to produce a spray-out sample before each refinishing job and tocompare it with the area to be repaired.

Stir the 923-55 and 923-57 clears well before use!

In order to avoid any gloss deviation when refinishing matt clearcoats, it is important• to observe the recommended film thicknesses for basecoat and clearcoat• to apply staggered overlaps to produce consistent basecoat and clearcoat film thicknesses.• to allow the clear to flash off until completely matt after each spraycoat. (Generally, after the first

spraycoat 10-15 min. and after the second spraycoat 15-20 min. That depends on air speed andspraybooth temperature.) Do not flash off for more than 25 minutes.

With matt surfaces it is not possible• to remove dust inclusions by polishing because polishing changes the gloss level. Therefore, it is

very important to work very carefully during cleaning and application.• to fade out the clear because the film thickness in the blending area varies, which changes the

gloss level. Therefore, always apply the clear to the whole panel!

Please also observe the technical product data sheets for Glasurit 923-55 MS Clear extra mat andGlasurit 923-57 MS Clear mat elastified.

TECHNICAL INFORMATION4. Mercedes-Benz-specific refinishing processes

4.4 Carbon fibre reinforced plastic (CRP)

Carbon fibre reinforced plastics consist of carbon fibre filaments embedded in epoxy resin. A characteristic feature of these materials is their very high stability at a low density. If these carbon fibre filaments are used for producing vehicle bodies or bodywork components, they are embedded in either colourless or tinted epoxy resin, depending on the application. Since the UV resistance of the epoxy resin is inadequate, the carbon fibre filaments are generally protected with two layers of clearcoat. The first clearcoat layer is intended to provide a visually smooth surface, and the second clearcoat layer is for UV protection. The latter is particularly important in the case of “visible carbon fibre”. Visible carbon fibre differs from topcoated carbon fibre in that the filaments are visible. A repair of visible carbon fibre only makes sense in the event of superficial damage which can be remedied by applying a clearcoat layer. In other words, the filament must not be damaged because otherwise the damage will remain visible. Repairing a topcoated carbon fibre component, on the other hand, does not call for any particular requirements. The standard refinish methods for metal surfaces or thermoset materials (SMC, GRP) incl. body filler can be used.

TECHNICAL INFORMATION5. Colour matching

5.1 Colour code labelling on rating plate

The first step when colour matching is always to identify the colour by checking the vehicle rating plate. The location of the plate can vary, depending on the particular vehicle model. In most Mercedes-Benz and smart models, however, the rating plate is on the B post (see figures). Older Mercedes vehicles sometimes also have stamped metal rating plates which can usually be found in the engine compartment.

Older series New series

The figures below show the respective locations of the rating plates with the paint code for old and current smart series. The colour number (A) is shown on the rating plate and is divided into two parts:

- The first three characters indicate the respective specification code for the Tridion safety cell (1) - The last three characters indicate the specification code for the standard plastic cladding (body panels, see 2)

1: Tridion safety cell specification code 2: Specification code for standard plastic cladding A: Rating plate

old smart series (450, 451) current smart series (453)


The second step when colour matching is, of course, to identify the correct colour formula (mixing formula). There are a number of ways of doing so:

- Via the Color Profi System

- Using a colorimeter

- Or directly via the internet (http://www.glasurit.com/de) using Color Online

To be absolutely sure, it is recommended that a spray sample of the identified solution be mixed and compared with the vehicle (colour) before carrying out the refinish job. A colour variant may have to be used to achieve a better colour match.
