About this product

Using this specific product

3M 3M Bondo 234D Ultimate Easy Sanding Body Filler is listed here as the Two-part body filler, CEEMEA data sheet version for auto body repair, dent filling, and sanding. For painting, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Two-part body filler, CEEMEA data sheet; related versions can use different timing.
  • For auto body repair, dent filling, and sanding, pay particular attention to surface preparation, coat thickness and ventilation.
  • At 25°C (77°F) with 2% hardener.

How to check readiness

Test an inconspicuous area for firmness and blocking before normal use. The data sheet gives a gel time of 3 to 5 minutes with 2% hardener. The data sheet gives 8 to 12 minutes before shape sanding. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.

Avoid this mistake

Recoating too early can trap solvent or water; waiting much longer may require scuffing under the label directions.
