The painter's daily work: from damage to invisible repair

A good paint job is judged by whether you can see it. A successful repair the customer does not notice — the transition to the old paint is invisible the gloss is uniform and the colour matches precisely. Behind that result lies a long and systematic workflow where the actual painting is often the quickest step. It is the prep work that determines the outcome.

§Reception and assessment of the damage

Work begins with assessing the damage. Is it a small stone chip, a dent from a collision or an entire side that needs to be repainted? The painter determines how deep the damage goes — whether it is only the clear coat or if the primer and sheet are damaged — and makes a plan for how large an area needs to be treated.

§Pre-treatment: where the battle is won

Pre-treatment is the trade's most important phase. The surface is cleaned of dirt wax and grease because even invisible residues destroy adhesion. Rust and loose paint are removed dents are corrected and unevenness is filled and sanded smooth. A smooth clean base is essential for the paint to settle evenly.

• 03Spackling of bumps and unevenness, then level sanding
• 04Covering of windows, trim and adjacent panels
• 05Primer that binds and levels the substrate

§The color on the electrode

Even the same factory colour can vary from car to car due to age sun fading and production. Therefore the painter often measures the car's actual colour and adjusts the mix until it matches. On metallic paint the effect must also match so the repair does not appear lighter or darker from the side. Often an adjacent panel is lightly coated as well so the transition fades out and becomes impossible to see.

§The actual painting

Painting happens in thin, uniform layers in a clean booth. First the base coat is applied, giving the color, then the clear coat, giving gloss and protection. The painter controls distance, speed and overlap with the gun so the layer is even without runs or orange peel. Between and after the layers, drying is controlled in the booth at controlled temperature.

§Finish and quality control

When the paint is dry, the surface is finished. Small impurities can be carefully sanded away and polished until the gloss matches the surrounding paint. Finally the result is checked in good light and from multiple angles—errors invisible in workshop light can jump out in sunlight. Only when the transition is invisible is the job done.
