How to Do Body Filler on a Car

Introduction

Body filler is a type of automotive repair material used to fill in dents, scratches, and other imperfections in a car’s body. It is a two-part system that consists of a resin and a hardener. When the two parts are mixed together, they create a chemical reaction that causes the filler to harden. Body filler can be applied to both metal and plastic surfaces.

Materials You Will Need

Before you begin, you will need to gather the following materials:

* Body filler
* Hardener
* Mixing stick
* Mixing bucket
* Sandpaper (various grits)
* Sander
* Masking tape
* Primer
* Paint

Safety Precautions

Body filler can release harmful fumes, so it is important to take the following safety precautions:

* Work in a well-ventilated area.
* Wear a respirator.
* Wear gloves.
* Avoid contact with skin and eyes.

Preparing the Surface

1. Clean the area to be repaired with soap and water.
2. Sand the area with sandpaper to create a rough surface. This will help the body filler to adhere to the surface.
3. Mask off the area around the repair with masking tape. This will protect the surrounding paint from damage.

Mixing the Body Filler

1. Add the resin and hardener to a mixing bucket according to the manufacturer’s instructions.
2. Stir the mixture thoroughly with a mixing stick until it is smooth and free of lumps.

Applying the Body Filler

1. Apply the body filler to the damaged area using a putty knife.
2. Spread the filler evenly over the area, using a slightly overlapping motion.
3. Allow the filler to dry for the time specified by the manufacturer.

Sanding the Body Filler

1. Once the body filler is dry, sand it with sandpaper to smooth it out.
2. Start with a coarse-grit sandpaper and gradually work your way to a fine-grit sandpaper.
3. Sand the filler until it is flush with the surrounding surface.

Priming the Body Filler

1. Prime the body filler with automotive primer.
2. Allow the primer to dry for the time specified by the manufacturer.

Painting the Body Filler

1. Paint the body filler with automotive paint.
2. Allow the paint to dry for the time specified by the manufacturer.
