Why Is Choosing the Right Filler Important for Bumper Scratches?
Selecting the appropriate filler for bumper scratches ensures a seamless repair and prevents additional issues. Using the wrong filler can lead to poor adhesion, uneven surfaces, and reduced durability. Here’s why the correct choice matters:
- Adhesion and Durability: The right filler adheres well to the bumper material, ensuring a long-lasting repair.

What Are the Types of Fillers for Bumper Scratches?
Understanding the different types of fillers can help you make an informed choice for your repair needs.
1. Polyester Resin Fillers
Polyester resin fillers are popular for their versatility and ease of use. They are ideal for minor to moderate scratches and dents.
- Advantages: Easy to sand, quick drying, and affordable.

2. Epoxy Fillers
Epoxy fillers are known for their strength and durability. They are perfect for deeper scratches and areas requiring more structural support.

3. Urethane Fillers
Urethane fillers are flexible and ideal for plastic bumpers. They adapt well to the bumper’s natural flex, preventing cracking.

How to Choose the Best Filler for Your Bumper?
Choosing the right filler involves considering the bumper material, the extent of the damage, and your repair skills.
