Understanding Bondo and Its Applications
Bondo is a two-part polyester body filler, commonly used for auto body repair. It’s known for its strength and ability to fill dents and imperfections, creating a smooth surface for painting.

Knowing when to use it and, more importantly, when not to use it, can save you time and frustration in the long run.
Preparing the Damaged Area for Bondo Application
Proper surface preparation is crucial for a successful Bondo repair. Thoroughly clean the damaged area with soap and water, removing any dirt, grease, or wax.
