For an auto body shop, choosing the right paint is not just a technical matter, but also an economic one. A wrong order means lost time, wasted materials, and, most seriously, a dissatisfied customer due to a repair with a noticeable shade difference. If you work with vehicles from individual or corporate clients, every paint order must be correct the first time—you cannot afford touch-ups or random mixes. Here's what you should look for when searching for a supplier and ordering automotive paint.

1. Color code — the basic information you need to request from the customer or identify yourself

Before any order, you need the car's color code. You usually find it:

• on the driver's door jamb;

• on the front passenger's door jamb;

• on the central (B) pillar, between the front and rear doors, on the driver's or passenger's side;

• in the engine compartment, on the identification label (e.g., on the shock absorber tower, front panel, or hood, depending on the manufacturer);

• in the trunk, under the carpet or in the spare wheel area;

• in the side compartment of the trunk (left or right), behind the trim;

• on the fuel cap or on the inside of the fuel flap (for certain models);

• in the service book or on the identification label in the vehicle's original documentation;

• in the manufacturer's electronic system, using the chassis series (VIN), at the brand dealership;

• in the official manufacturer's app, for some modern models.

For a workshop, it's useful to have a clear workflow: either ask the client to send a photo of the label when scheduling, or identify the code yourself upon vehicle reception. A good paint supplier offers a catalog of codes by brand (BMW, Audi, Mercedes, Dacia, Toyota, etc.) that is easy to search, ideally with an online quick search tool—this shortens the time from vehicle reception to the actual order.

However, remember: the color code is a starting point, not a guarantee. The same code can cover shade variations between manufacturing batches, which is why it's worth working with a supplier who also offers additional color verification, not just "by code" paint.

2. Spectrophotometer verification — a criterion for choosing a supplier

If you want to reduce complaints related to shade differences, it matters whether the supplier you buy from (or send the car/sample to) has a spectrophotometer and can generate a formula adapted to the car's actual color, not just the code in the catalog.

This is especially relevant for orders for:

• older cars with faded paint;

• partial touch-ups, where the shade difference is immediately visible next to the original bodywork;

• demanding clients who refuse the repair if the shade doesn't match perfectly.

When looking for a supplier, explicitly ask if they offer this service (color identification with a spectrophotometer, possibly on-site or by sending a sample)—it's a criterion that can make the difference between a reliable partner and one who just sells "by code" paint, without guarantees.

3. Solvent vs. water, 1K vs. 2K — choose based on the type of work in your shop

The type of paint you order should correspond to your workshop's work profile and your equipment (paint booth, ventilation, drying):

• Solvent-based paint — easy to apply, fast drying, suitable for high volumes of work and routine touch-ups.

• Water-based paint (waterborne) — increasingly required due to environmental regulations; needs more controlled drying conditions, thus appropriate equipment in the workshop.

• 1K (single-component) — practical for quick touch-ups and small volumes, but with lower durability—useful if you want to keep costs and working times low for minor repairs.

• 2K (two-component, with hardener) — the standard for jobs that need to last over time (scratches, UV, washing); costs a little more and requires mixing time, but reduces the risk of subsequent complaints.

If you have a mixed client flow—from quick touch-ups to complete repairs—it's worth working with a supplier who has a constant stock of both variants, so you don't have to delay work due to lack of product.

4. Don't just buy the color — order the complete system

A mistake that costs money and time in the workshop is ordering only the base paint, without the rest of the compatible components. For a correct job, you need:

1. Primer — for adhesion and surface leveling.

2.  1K basecoat.

3. Clearcoat — protection, gloss, UV resistance.

4. Hardener — mandatory for 2K systems.

5. Thinner — for adjusting viscosity, depending on the spray gun and booth conditions.

When looking for a supplier, check if they can deliver the entire system from the same product line (guaranteed compatibility), not just the base paint separately. Mixing components from different brands or generations increases the risk of peeling or adhesion problems—a risk that a serious workshop cannot afford, especially for jobs billed to the client with a warranty.

Practically, for any order, it's useful to work with a supplier where you can order the entire package at once—primer, basecoat, clearcoat, hardener, thinner—without having to search multiple suppliers for compatible components.

5. Car age and sun exposure — an additional reason to check, not just order "by code"

For a workshop, it's important to explain (or anticipate) to clients that original paint fades over time due to UV radiation, washing, and environmental exposure. An order placed strictly according to the color code can appear visibly different from the actual bodywork, especially for:

• cars older than 5-7 years;

• panels constantly exposed to the sun, unlike the rest of the car;

• intense colors (red, dark blue, black), where fading is more visible.

Therefore, for orders for older cars or partial touch-ups, additional shade verification (spectrophotometer or physical sample sent to the supplier) significantly reduces the risk of a wrong order—and, implicitly, of a dissatisfied client or a repair redone at the workshop's expense.

Conclusion: what to actually look for in an automotive paint supplier

For an auto body shop, choosing the right paint translates into choosing a supplier who offers:

• a complete color code catalog, easy to search by make/model;

• the possibility of checking the actual shade (spectrophotometer, samples);

• constant stock of solvent and water-based, 1K and 2K variants;

• complete and compatible systems (primer, basecoat, clearcoat, hardener, thinner), not just the base color;

• consultancy for difficult cases—old cars, faded colors, partial touch-ups.

A supplier who checks all these boxes shortens your ordering time, reduces the risk of customer complaints, and, in the long run, protects your workshop's reputation.
