How to Paint Brake Calipers with a Spray Can Kit

Classic reds and yellows or any custom color — durable, brake-dust-resistant, painted on the car.

What's in the box

  • 1 color spray can
  • 1 × 1K Epoxy Primer/Sealer can (gray or black to suit your color)
  • 1 × 2K clearcoat can (gloss or matte)
  • 2 gray scuff pads
  • Q1 yellow masking tape, 1.5" and 0.75"
  • Masking drop film (tape & drape)

Coverage: one kit does a complete set of four calipers (11–12"). White and other light ground-coat colors add a Wicked White can.

Before you buy: pitted or corroded calipers need High Build Primer first.

Safety First

2K clear contains isocyanates. Spray with good airflow, and wear a paint-rated respirator, gloves and goggles every time.

Step by step: caliper

  1. Wash off brake dust and grime

    Wash the calipers with soap and water, a wheel cleaner like our Dust-Destroying Wheel Cleaner and a scrubber mitt until all brake dust and grime is gone.

  2. Dry and wipe clean

    Dry, then wipe with isopropyl alcohol or Sprayway Cleaning Spray.

  3. Scuff fully

    Scuff the whole caliper with the gray scuff pads until it is flat and evenly scratched.

    💡 Pitted or corroded? Spray High Build Primer now, let it dry, and sand it 320–400 before the epoxy.

  4. Rinse and dry

    Rinse, then dry with a clean rag and compressed air.

  5. Mask rotors, lines and hardware

    Use the drop film and tape to mask the rotors, brake lines and hardware. No tape bridging onto the caliper.

  6. Final wipe

    Wipe again with a clean microfiber and isopropyl alcohol.

  7. Spray the epoxy primer/sealer

    Shake the 1K Epoxy Primer/Sealer can for 45–60 seconds. Spray 1 light coat on each caliper, wait 5 minutes, then 1 medium wet coat.

    💡 Keep shaking the can between coats. Cold can? Warm it in a bucket of warm water first — never heat it.

  8. Wait 1 hour

    Let the primer get 100% dry to the touch, then wait 1 hour before basecoat. No sanding needed inside 24 hours.

  9. Spray the basecoat

    Shake the color can for 45–60 seconds. Spray 2–4 medium coats, 10 minutes (or until matte) between coats, until you have full color and an even effect.

    💡 Metallics and pearls: finish with one light control coat so the flake lays evenly.

  10. Wait 30 minutes to 1 hour

    At 70°F or warmer, spray clear 30 minutes to 1 hour after the entire surface, even cracks and crevices, is completely dry to the touch.

  11. Spray the 2K clearcoat

    Activate the 2K can: flip it, remove the plug and pull off the metal ring, put the ring through the lug on the bar, then pull out and turn 360°. Shake hard for 45–60 seconds, then spray 2–3 wet coats. Recoat when the masking feels fingerprinty (about 10 minutes) and check the masking between coats.

    💡 Activate the clear only when you are ready to spray — it has a 24 hour pot life.

  12. Unmask after 30 minutes

    Pull the tape and masking off after 30 minutes, while the clear is still soft, so it leaves a clean edge.

  13. Let it cure 8 hours

    Give it 8 hours before refitting the wheels and 12 hours before polishing. Flip every can upside down and spray until it runs clear so the nozzle is saved for next time.
