Preparing the Dent for Bondo Application
Proper surface preparation is crucial for successful Bondo application. Start by cleaning the dented area thoroughly with soap and water, then degrease it with a wax and grease remover. Next, sand the area around the dent with coarse grit sandpaper (80-grit) to remove any loose paint and create a rough surface for the Bondo to adhere to. If rust is present, remove it completely using a wire brush or sandpaper before proceeding. This crucial step ensures the Bondo bonds effectively and minimizes the risk of further rust development.

How to Properly Mix Bondo

Dispense the appropriate amount of Bondo resin and hardener according to the manufacturer’s instructions. Mix thoroughly until a uniform color is achieved, ensuring no streaks of hardener remain. Work quickly, as Bondo has a limited working time once mixed.

Applying and Shaping the Bondo
Apply the mixed Bondo to the dented area using firm, even strokes, overlapping each pass slightly. Build up the Bondo slightly higher than the surrounding surface to allow for sanding. Allow the Bondo to cure completely according to the manufacturer’s instructions. Once cured, shape the Bondo using a sanding block and progressively finer grits of sandpaper (80-grit, 180-grit, and then 320-grit). Aim for a smooth, even surface that blends seamlessly with the surrounding body panels.

Sanding is perhaps the most critical step in achieving a professional-looking repair when fixing dents in a car with Bondo.

Priming and Painting the Repaired Area
After sanding, apply a thin coat of primer to the repaired area. This seals the Bondo, provides a uniform surface for paint adhesion, and helps prevent rust. Once the primer dries, lightly sand it with fine-grit sandpaper (400-grit or higher) to create a smooth surface for the paint. Finally, apply several thin coats of paint, allowing each coat to dry completely before applying the next. Consider a clear coat for added protection and shine.
