How to Paint Cars in Car Mechanic Simulator (Paintshop Guide)
Car Mechanic Simulator paints cars through the in-game Paintshop — no real spray gun or body filler, just a color menu and a part-isolation rule that trips up new players. Miss that rule and the game won’t let you paint the part you’re holding, even with the Paintshop unlocked. This guide covers the HSB color and finish options, fixing rust before painting, why parts refuse to paint, and what’s new in Car Mechanic Simulator 2026.
Quick Answer
Painting happens at the Paintshop station: park the whole assembled car inside to repaint the entire vehicle, or pull one part into your inventory and paint it alone with the car parked outside the booth. Color uses Hue/Saturation/Brightness sliders (not RGB), with factory-color matching, metallic, and pearlescent finishes once the room is unlocked.
How to Paint a Car in Car Mechanic Simulator (Step by Step)
This is the whole-car process from a clean, rust-free vehicle to a finished paint job. Painting an individual part on its own follows the same color and finish choices in step 4, but uses the isolation setup covered later in this guide.
- Repair or remove rust: Weld rust on the frame or main body in place, or remove and repair/replace any rusted panel at the repair table.
- Assemble the car fully: Reattach every part you took off during repairs — a part missing from the car will block painting the whole vehicle.
- Drive the car into the Paintshop: Park the fully assembled car inside the Paintshop bay.
- Pick a color and finish: Use the HSB sliders for a custom color, or tick the factory color box, then choose a flat, metallic, or pearlescent finish.
- Apply the livery (optional): Open the last tab in the paint interface to add two-tone splits, stripes, or decals on top of the base color.
- Paint individual parts separately (optional): Remove any part you want a different color, keep it in your inventory with the car outside the Paintshop, then repeat the color step for that part alone.
What Is the Paintshop in Car Mechanic Simulator?
The Paintshop is a dedicated garage station in Car Mechanic Simulator that changes a car’s paint color and finish. It works two ways: painting the entire assembled car at once, or painting a single removed part on its own. The room has to be unlocked through the game’s skill and progression system before either option becomes available.
Painting the Whole Car vs. Painting Individual Parts
The two paint modes use opposite setups, and mixing them up is the most common reason painting doesn’t work the way new players expect. To repaint an entire car, the fully assembled vehicle needs to be parked inside the Paintshop bay — every panel gets the same color and finish in one pass. To repaint a single part — a hood, bumper, fender, rim, caliper, or many engine components — remove it from the car first and make sure it’s sitting in your parts inventory, with the rest of the car parked outside the Paintshop. The game won’t paint a part that’s still attached to a car sitting in the booth, and it won’t paint the whole car if a part you meant to isolate is still bolted on.
| Mode | Car location | What gets painted | Common use |
|---|---|---|---|
| Whole car | Inside the Paintshop, fully assembled | Every visible panel | Full respray, mission requirement |
| Individual part | Removed, sitting in parts inventory; car parked outside | Just that one part | Color-matching a replacement part, rims, calipers |
How to Choose Paint Colors, Finishes, and Liveries
Paint color is set with Hue, Saturation, and Brightness (HSB) sliders rather than RGB values or a swatch book. Drag each slider until the preview matches what you want, or skip the sliders entirely by ticking the factory color box near the top of the paint screen — this pulls the car’s original manufacturer code instead of a custom mix, which matters for restoration jobs and for keeping a car’s parts-compliance rating, and resale value, intact.
Metallic, Pearlescent, and Matte Finishes
Beyond the base HSB color, the Paintshop offers metallic and pearlescent finish options alongside a standard flat finish. Metallic adds a flake-like shimmer that reads well in direct light. Pearlescent adds a subtler color-shift effect, though several longtime players note it’s a less dramatic effect in-game than the name suggests. Try both on a cheap part before committing an entire respray to either one.
Using the Livery and Sticker Tab
The last icon at the top of the paint interface — the one that looks like a set of stacked lines — opens the livery and sticker tab. This is where two-tone splits, racing stripes, and decal-style graphics get applied on top of whatever base color and finish you already picked, separate from the color sliders themselves.
How to Remove Rust Before You Paint
Rust has to be dealt with before a panel will accept paint, but the fix depends on where it is — and it isn’t sandpaper. Rust on the frame or main body structure, the areas that can’t be unbolted, is cleared with the welder tool. Rust on a removable panel — a fender, door, bumper, or hood — can’t be welded clean; that panel has to come off the car and get repaired at the repair table, which needs a high repair skill level, or be replaced outright with a new part.
| Where the rust is | How to remove it | Note |
|---|---|---|
| Frame / main body | Welder tool | Works in place, no need to remove the frame |
| Removable panel (fender, door, bumper, hood) | Repair table (needs high repair skill) or full replacement | Panel has to come off the car first |
Why Won’t Car Mechanic Simulator Let Me Paint My Part?
This is the single most common Paintshop complaint, and it almost always comes down to isolation, not a bug. If painting won’t work, check these in order.
| Symptom | Likely cause | Fix |
|---|---|---|
| The whole car won’t paint | A part is missing or still marked for removal | Reassemble every part, then re-enter the Paintshop |
| A single part won’t paint | The part is still attached to the car, or the car is still inside the Paintshop | Remove the part fully into your inventory and move the car out of the booth |
| Paint option is grayed out entirely | The Paintshop room hasn’t been unlocked yet | Progress through the relevant skill or reputation tier to unlock it |
| A steering wheel or seat won’t register a new color | Some interior parts have had inconsistent paint registration reported by players | Re-enter the Paintshop or reselect the part before repainting |
What’s New in Car Mechanic Simulator 2026’s Paintshop?
📊 A single-player demo of Car Mechanic Simulator 2026 — including its Paintshop and new Window Tinting station — has been downloadable on Steam since March 30, 2026, ahead of the game’s full release planned for later in 2026. — Source: Car Mechanic Simulator 2026, official Steam store page
Car Mechanic Simulator 2026 keeps the same whole-car-vs-individual-part Paintshop split as earlier games, but adds a Window Tinting station next to it, and tracks a car’s Body Condition and Frame Condition as two separate percentages instead of one combined score. The 2026 entry also adds co-op play, letting two players run the same workshop — including the same paint jobs — together.

Frequently Asked Questions
Why won’t Car Mechanic Simulator let me paint my part?
Because the part is still attached to the car, or the car itself is still sitting inside the Paintshop. Pull the part completely into your inventory and move the car out of the booth first — the game paints a whole assembled car or one isolated part, never a mix of both at the same time.
Does Car Mechanic Simulator use RGB sliders for paint color?
No. The Paintshop’s color picker uses Hue, Saturation, and Brightness (HSB) sliders instead of RGB values. You can also skip manual color mixing entirely by ticking the factory color option, which applies the car’s original manufacturer paint code.
How do you remove rust before painting in Car Mechanic Simulator?
It depends on the location. Rust on the frame or main body is cleared with the welder tool without removing anything. Rust on a removable panel — a fender, door, bumper, or hood — requires taking that panel off and repairing it at the repair table or replacing it outright.
Can you paint individual car parts separately in Car Mechanic Simulator?
Yes. Remove the part you want to color and keep it in your parts inventory, with the rest of the car parked outside the Paintshop. Rims, calipers, suspension components, the gas tank, and many engine parts can all be painted this way.
Does Car Mechanic Simulator 2026 change how painting works?
The core Paintshop mechanic — whole car or isolated part — stays the same, but 2026 adds a Window Tinting station alongside it and tracks Body Condition and Frame Condition separately. As of August 2026 the game is still pre-release, with only a single-player demo available since March 30, 2026 ahead of a full launch later in the year.
Are metallic and pearlescent paint finishes available in Car Mechanic Simulator?
Yes, both are selectable alongside the standard flat finish in the Paintshop. Metallic adds a flake shimmer; pearlescent adds a subtler color-shift effect that some players find less pronounced than its name implies.
Final Thoughts
Most Car Mechanic Simulator painting problems trace back to one rule: paint the whole assembled car, or paint one isolated part — never a mix of the two. Get that straight, match rust removal to where the rust actually is, and the HSB color picker and finish options handle the rest. Watch Car Mechanic Simulator 2026’s demo for how the new Window Tinting station and co-op painting change things once the full game lands.
