Instructions (step-by-step)

  1. Safety

    • Wear gloves and eye protection.
    • Work in a well-ventilated area.

  2. Resin Finishing Layer

    • Mix resin and hardener as usual.
    • Apply a thin finishing coat with a brush over the cured carbon surface.
    • Smooth out imperfections.
    • Allow resin to fully cure.
    • Clean the brush immediately after use.

  3. Optional Sanding

    • If a smoother or glossier surface is desired, sand the cured resin lightly.
    • Start with 400 grit, then move to 600 grit.
    • Finish with 1000 grit if you want a mirror-like polish.
    • Skip this step if surface smoothness is not critical.

  4. Optional Decal Application

    • Print the logo onto the back of vinyl sticker paper. Download the printable logo

    • Cut out the design.

    • Apply the decal carefully onto the carbon surface.

  5. Clear Coat

    • Spray the entire surface with acrylic clear coat.
    • Apply 3 light, even layers.
    • Allow proper drying time between layers.

Limitations

  • Requires time and patience for curing and sanding.
  • Gloss finish depends on sanding quality and spray application.
