How to Use 3M Bondo 261 Effectively

Applying 3M Bondo 261 requires a bit of skill and practice, but with the right technique, achieving a smooth and durable finish is achievable:

  1. Preparation:

    • Clean the damaged area thoroughly with a degreaser or solvent to remove any dirt, oil, or contaminants.
    • Use sandpaper to roughen the surface, creating a good bonding surface for the filler.
  2. Mixing:

    • Mix the filler with the hardener in the correct ratio, according to the manufacturer’s instructions.
    • Ensure a thorough and consistent mix to achieve the desired hardening time and strength.
  3. Application:

    • Use a putty knife or a body filler spreader to apply the mixed filler to the damaged area.
    • Work the filler into the contours of the bodywork, ensuring that it fills all gaps and imperfections.
  4. Smoothing and Shaping:

    • Once the filler has begun to set, use a putty knife or a body filler spreader to shape and smooth the surface.
    • Avoid excessive pressure, as this can damage the filler.
  5. Drying:

    • Allow the filler to dry completely according to the manufacturer’s instructions. This usually takes several hours.
  6. Sanding:

    • Once dry, sand the filler using various grades of sandpaper to achieve a smooth and consistent surface.
    • Start with coarse sandpaper to remove any high spots and then gradually transition to finer grades to achieve the desired finish.

It’s essential to prepare the surface properly for optimal results. This includes cleaning the area and roughening the surface with sandpaper. Once the filler is mixed and applied, you can shape and smooth the surface before allowing it to dry completely. Finally, sanding the filler with different grades of sandpaper will achieve a smooth and consistent finish.
