Safety Precautions
Before you begin working with Bondo, it is important to take some safety precautions. Bondo is a hazardous material that can cause skin irritation, eye damage, and respiratory problems. It is important to wear gloves, eye protection, and a dust mask when working with Bondo. You should also work in a well-ventilated area.
Step-by-Step Instructions
To repair a car body with Bondo, follow these step-by-step instructions:
1. Clean the damaged area. The first step is to clean the damaged area with a degreaser to remove any dirt or grease. Once the area is clean, dry it thoroughly with a clean cloth.
2. Mask off the area. Use masking tape to mask off the area around the damaged area. This will help to protect the surrounding paint from damage.
3. Mix the Bondo. In a mixing cup, mix together the Bondo and hardener according to the manufacturer’s instructions. The ratio of Bondo to hardener will vary depending on the brand of Bondo that you are using.
4. Apply the Bondo. Use a putty knife to apply the Bondo to the damaged area. Spread the Bondo evenly and smooth it out with the putty knife.
5. Sand the Bondo. Once the Bondo has cured, sand it down with 80-grit sandpaper. Use a sanding block to help you sand evenly. Once the Bondo is smooth, sand it with 120-grit sandpaper and then 220-grit sandpaper.
6. Primer the Bondo. Apply a coat of primer to the Bondo. This will help to protect the Bondo from moisture and will also help the paint to adhere to the Bondo.
7. Paint the Bondo. Once the primer has dried, paint the Bondo to match the rest of the car.
