Junk Mechanics Paint Shop and Customization Guide

A fresh paint job is the step that turns a repaired car into a sellable one, and the customs shop is also where you make your own cars look the way you want. This guide covers the paint process, every material and option added through October 2026, and which of them matter for selling.

Quick answer

Always paint before selling: polish off the rust, fill every marked panel, pick a colour, then confirm

Drive into the paint and customs shop (heard in videos as Los Alamos Customs), accept the paint restore prompt, hold left click on the car to polish away the rust, then fill in every marked panel such as the roof and trunk. Pick a colour (you can paste a hex code) and a material. Money guides agree that skipping paint noticeably lowers a car's sale value. The rest of the customs menu (secondary colours, carbon and chrome materials, plates, tint, underglow, horns, hidden hoods and doors) is for cars you keep.

How to paint a car, step by step

  1. Finish the mechanical repairs first (see the repair guide); painting is the last step before selling.
  2. Drive into the paint and customs shop and accept the prompt to restore the car's paint. An early-August playthrough showed this as free on the first car and $250 on a later car, so expect a small fee.
  3. Hold left click on the car to polish it. Keep going until no brown rust patches are left.
  4. Paint every marked area. The game treats this as a small task, so panels such as the roof and trunk must each be filled in.
  5. Choose a colour. The picker sometimes starts on a default such as yellow; change it if you like. You can copy and paste hex codes, which is how creators share exact colours.
  6. Pick a material, confirm, and drive to a buyer.

Paint materials and colours

The paint menu has grown with almost every update. Materials apply to the primary colour and, since the late-August update, to a secondary colour as well. Secondary colour is how players do two-tone looks, stripes on muscle cars, and contrasting hoods.

Paint materials and when they were reported
Material or optionWhat it looks likeFirst reported
Default (gloss)Standard solid paintLaunch
MetalMetallic finishAugust 2026 build videos
FlakeSparkly metal-flake finish, popular on redsAugust 2026 build videos
MatteFlat finish; creators prefer it in black or whiteAugust 2026 build videos
Secondary colourA second paint zone with its own materialAugust 30, 2026 update
Carbon fiberCarbon weave; often used for hoodsSeptember 5, 2026 update
Carbon camo and forged carbonPatterned carbon looks that are close to each otherSeptember 5, 2026 update
ChromeMirror finish, usable as a full wrapSeptember 5, 2026 update

A carbon hood is the classic combination: set the hood as the secondary zone and give it the carbon fiber material while the body keeps a gloss or flake colour. Interiors could not be recoloured when this page was checked.

Plates, tint, underglow and horns

The August 16 update opened up several cosmetic options to every player. Before that, custom plates were reported as a content-creator perk.

  • License plates: change the characters and add small symbols such as stars or hearts. There is also an NPC near the start area who offers custom plates.
  • Window tint: set as a percentage; a creator used about 14% on a classic supercar.
  • Underglow: coloured lights under the car.
  • Horns: several horn sounds to choose from.

None of these are needed for a flip. They are for cars you keep, show off, or use for videos.

Hiding hoods, doors, bumpers and body panels

Two recent updates added body-panel options in the customs menu. On cars that support it you can:

Body-panel options by update
OptionUpdateNotes
Hide the hoodSeptember 26, 2026Shown on a muscle car; not every model supports it.
Remove the frunk and engine glassSeptember 26, 2026Shown on a remodelled mid-engine supercar that also gained an interior.
Hide the doorsOctober 3, 2026Good for off-road builds.
Remove the rear bumperOctober 3, 2026Available on some cars only.

Opening doors and hoods as you walk around a car came earlier, in the September 12 update, so do not confuse opening a door with hiding it. If an option is missing, the car you are in probably does not support it yet.

Once your build looks right, the wheels, tires and suspension guide covers fitment and ride height, and the tuning guide covers performance.

Frequently asked questions

Does painting increase sale value in Junk Mechanics?

Yes. Every money guide we checked says a fresh paint job is one of the biggest value jumps and that skipping paint lowers the offer.

How do you remove rust in Junk Mechanics?

At the paint shop, hold left click on the car to polish it until no rust patches are left, then paint every marked panel.

Can you do two-tone paint?

Yes. The August 30 update added secondary colours, each with its own material, so you can do stripes, a contrasting hood, or a two-tone body.

How do I get a carbon fiber hood?

Since the September 5 update, carbon fiber is a paint material. Set the hood as the secondary zone and apply carbon fiber to it.

How do I remove doors or the hood?

Use the customs menu. Hood hiding came on September 26 and door or rear-bumper removal on October 3, on supported cars only.

Sources and how this page was checked

Paint steps come from early playthroughs that show the paint prompts on screen. Each customization option is dated to the update video that first showed it, from August 16 to October 3, 2026. We have not measured whether a specific colour or material changes a dealer's offer, so this page makes no colour-for-profit claims.
