“A beautiful car must have perfect form,” says Tuan, the owner of a car repair shop on Nguyen Trai Street, Ha Dong, when asked about his secret to car care. And one crucial step to achieving that “perfect form” is applying car body putty.

Applying putty is a vital step in the car painting process, ensuring a smooth surface for even and durable paint application. However, not everyone understands the proper process and techniques for applying putty correctly. In this article, XE TẢI HÀ NỘI will guide you through the A to Z of car body putty application, giving you the confidence to care for your vehicle.

1. What is Car Body Putty? Its Role in Car Painting

1.1. What is Car Body Putty?

Car body putty is a filling material, available in powder or paste form, used to smooth out rough surfaces, dents, and scratches on a car body before painting.

1.2. The Role of Car Body Putty

Putty plays a crucial role in the car painting process because it:

• Creates a smooth surface for paint: Putty fills imperfections on the metal surface, creating a smooth base for even and flawless paint application.
• Prevents rust: The putty layer acts as a protective barrier, preventing direct contact between the metal and air and water, thus limiting oxidation and rust formation.
• Enhances paint durability: The smooth surface after putty application allows the paint to adhere better, increasing its durability and reducing peeling and cracking.
