How to Apply Car Body Filler

Preparation

2. Mix thoroughly⁚ Use a mixing stick or spatula to thoroughly combine the filler and hardener until a uniform consistency is achieved.

Applying the Filler

3. Let it dry⁚ Allow the filler to dry completely according to the manufacturer’s instructions. This typically takes several hours.

Sanding and Finishing
