Should bare metal be cleaned with a wax and grease remover before applying body filler?

Cleaning bare metal with a wax and grease remover before applying body filler is essential to ensure proper adhesion between the filler and the metal surface. The remover effectively eliminates any contaminants, including oil, grease, and dirt, that could interfere with the bonding process. If these substances are present, they can prevent the filler from adhering correctly, leading to potential issues like peeling or cracking over time.

When bare metal surfaces are prepared, it is crucial to ensure they are thoroughly cleaned to create a suitable environment for the body filler. While it's important to assess the specific conditions of the surface before applying any materials, the general practice is to clean the area to maximize the chance of a successful and durable repair.
