How to properly paint a chip on a car: a detailed guide with photos

• 🏬 Specialty stores (Autocolor, Mobihel, Spectrum-Auto).
• 🛒 Online services (AvtoKraska.ru, PaintScratch) — paint is sent by mail with a guarantee of color matching.
• 🔧 Car services (many offer the sale of paint without work).

If you are not sure about the color accuracy, order sampler (10-20 ml) and apply paint to an unnecessary part (for example, the inside of the hood) to test.

3. Tools and materials: what you need for work

To paint a chip with high quality, prepare the following set:

Matching paint (by color code)|Primer (for deep chips)|Varnish (if using acrylic enamel)|Sandpaper P1200–P2000|Degreaser (White spirit or Antisilicone)|Making tape and film|Brush or airbrush|Polishing paste (3M, Meguiar’s)|Gloves and respirator-->

⚠️ Attention: do not use acetone or solvent 646 for degreasing - they can damage the factory paintwork. The best option is Isopropyl alcohol (70% and above).

For grinding it is better to take waterproof sandpaper — it can be moistened with water to avoid dust and overheating of the surface. If the chip is on aluminum parts (for example, on Audi A6 or Jaguar XE), use aluminum oxide instead of a regular abrasive - it is softer and does not scratch the metal.

4. Surface preparation: grinding, degreasing, masking

Depends on the quality of preparation 90% success painting. If you skip this step, you risk paint peeling or bubbles. Follow the steps:

1. Washing and drying: Wash the car thoroughly with car shampoo (for example, Karcher), then dry the surface with a lint-free cloth. Avoid direct sun - moisture should evaporate naturally.
2. Grinding the chip:
   • For small chips (up to 2 mm) just sand the edges P2000to remove burrs.
   • For deep damage use the sequence: P800 → P1200 → P2000. Sand in a crisscross pattern to avoid waves.
• Degreasing: apply antisilicone onto a lint-free cloth and wipe the area around the chip (radius 10–15 cm). Do not touch the surface with your hands after this procedure!
• Disguise: Cover the surrounding parts with masking tape and film. For curved surfaces (for example, on BMW 3 Series) use liquid masking film — it follows the contours of the body.

What to do if there is a chip on rusty metal?

If rust is visible in the chip, first apply rust converter (for example, Hi-Gear or Permatex), then after 10–15 minutes, rinse it off with water and dry the surface. After this, treat the area acid soil (for example, Reoflex) for better paint adhesion.

5. Painting technology: step-by-step instructions with photos

Now we move on to the most important stage - applying paint. The method depends on the size of the chip and the chosen tool.

Option 1: Brush or toothpick (for chips up to 3 mm)

1. Apply thin layer of primer (if the metal is bare) using a toothpick. Let dry 15–20 minutes.
2. Carefully fill the chip with paintwithout going over the edges. Hold the brush at an angle 45°to avoid leaks.
3. Let the first layer dry 10 minutes, then apply a second one. For metallic you will need 3–4 layers.
4. After drying (after 1–2 hours) apply varnish (if acrylic enamel is used).

Option 2: Airbrush or spray can (for chips from 5 mm)

1. Step back from the surface 15–20 cm and apply paint short sprays (by 1–2 seconds).
2. Move the can parallel to the surfaceto avoid “dust” (fine splashes).
3. Apply 2–3 layers at intervals 5–7 minutes. The last layer should be the thinnest.
4. For mother of pearl or chameleon after the base coat, apply clear varnish in 2 layers.

6. Drying and polishing: how to achieve factory shine

Even perfectly applied paint will look dull without finishing. Rules for drying and polishing:

• ⏳ Drying time:
  • Acrylic enamel: 24 hours until completely cured.
  • Alkyd enamel: 48–72 hours (can be accelerated with an infrared lamp).
  • Varnish: 12–24 hours (do not touch with your hands!).
  • 🌡️ Terms: the room temperature should be 20–25°C, humidity - no higher 60%. Avoid drafts and dust.
  • 🔦 Polishing:
    1. Start with abrasive paste (for example, 3M 09374) and a soft wheel on a grinder (rev. 1000–1500 rpm).
    2. Then use restorative paste (for example, Meguiar’s Ultimate Compound) to restore shine.
    3. Complete protective polish (for example, Ceramic Coating) for durability.

  ⚠️ Attention: if there are any left after polishing matte spots, this means that the varnish has not yet dried or you used too hard a circle. In this case, repeat polishing after 2–3 days with a less abrasive paste.

  7. Common mistakes and how to avoid them

  Even with careful preparation, beginners often make mistakes that spoil the result. Let's look at the most common ones:

  Error	Consequences	How to avoid
  Applying paint to a dirty surface	Peeling, blisters	Use antisilicone and don't touch with your hands
  Too thick layer of paint	Smudges, long drying time	Apply 2–3 thin layers at intervals
  Painting in direct sunlight	Uneven drying, spots	Work in the shade or in a ventilated garage
  Using a cheap brush	The lint remains on the paint	Take synthetic brushes for modeling
  Skipping primer on deep chips	Corrosion, poor adhesion	Always prime bare metal

  🔧

  💡

  If there are any left after painting small irregularities, do not try to sand them right away. Wait 3–5 days - the varnish will finally harden, and defects will be easier to remove.

  8. FAQ: answers to frequently asked questions

  Is it possible to paint chips in winter?

  You can paint, but with reservations:

  • The room temperature should not be lower than +15°C.
  • Use quick-drying enamels (for example, SprayMax 2K).
  • Drying time will increase by 1.5–2 times.

  Paint outside in winter it's impossible — moisture and cold will lead to paintwork defects.

  How long does spray paint last?

  With proper preparation and application:

  • Acrylic enamel: 2–3 years no visible changes.
  • Metallic with varnish: 3–5 years (subject to polishing once a year).
  • Corrector pencil: 6–12 months (washable).

  Service life depends on quality of training and operating conditions (garage/street).

  What is the difference between a retouching pencil and paint?

  Touch-up pencil (eg. Touch-Up Paint from Dupli-Color):

  • ✅ Convenient for small chips (up to 1–2 mm).
  • ✅ Does not require preparation (can be applied directly to the chip).
  • ❌ Short-lived (washed off after 5–10 washes).
  • ❌ Not suitable for deep damage.

  Regular paint lasts longer but requires sanding and varnishing.

  Is it possible to paint a chip without varnish?

  It's possible, but:

  • Without varnish there will be paint less stable to UV rays and chemicals (for example, bird droppings).
  • Acrylic enamel without varnish it fades through 1–2 years.
  • Metallic without varnish it looks matte and loses the “depth” of color.

  For temporary repairs, varnish is not necessary, but for longevity it is better to apply it.

  How to remove smudges after painting?

  Leaks appear due to:

  • Too thick paint.
  • Applications in hot weather.
  • Incorrect distance when spraying.

  How to fix:

  1. Wait for it to dry completely (24–48 hours).
  2. Gently sand away the stain with sandpaper. P2000 with water.
  3. Polish the place restorative paste.
