For an automotive workshop, painting and lacquering are not interchangeable, and treating them as a single step (or ordering a single "does it all" product) frequently leads to subpar results. Here's why the two layers have distinct roles and why, in automotive two-component systems, clear coat is not optional.

1. Painting provides the color

The base coat (the actual paint) is what contains the pigments and provides the color and, depending on the formula, special effects (metallic, pearlescent). Its main role is aesthetic — matching the exact shade with the rest of the bodywork.

2. Lacquering protects and provides gloss or a matte finish

The clear coat is the transparent layer applied over the color base. Its role is not aesthetic in terms of color, but protective — and, secondarily, for the finish (gloss level: glossy, satin, matte). Without clear coat, the color layer remains directly exposed to UV, scratches, and chemical agents, which quickly leads to discoloration and degradation.

3. In automotive two-component systems, clear coat is essential

For most modern automotive paints (basecoat + 2K clear coat), the basecoat is not formulated to resist alone outdoors over time — it is designed to be covered by clear coat. Omitting the clear coat or using a clear coat incompatible with the base system compromises both the appearance and the durability of the repair, no matter how well the color was matched.

4. How clear coat influences UV resistance, scratch resistance, and final appearance

The quality and type of clear coat largely determine how well the repair holds up over time:

• UV resistance — a quality clear coat reduces discoloration and dulling of the surface over time, especially for cars constantly exposed to the sun;

• scratch resistance — high-quality HS/UHS clear coats provide a harder film, more resistant to washing and micro-scratches;

• final appearance — the gloss level and clarity of the clear coat directly influence how "invisible" a touch-up is next to the original paint.

What to order together

For a complete and durable job, always order the basecoat and clear coat as a compatible system, plus the appropriate hardener for the clear coat (fast, standard, or slow, depending on available time and workshop conditions and ambient temperature). A clear coat chosen only by price, without compatibility with the basecoat used, is one of the most frequent causes of complaints about uneven gloss or low durability.
