How to Fix a Crack in Your Plastic Dashboard: A DIY Guide

Understanding Dashboard Cracks

Cracks in plastic dashboards are a common issue in older vehicles, often caused by prolonged exposure to sunlight and extreme temperatures. These unsightly blemishes can detract from your car’s interior aesthetics and potentially worsen over time. Fortunately, with the right materials and techniques, you can repair these cracks yourself and restore your dashboard’s appearance.

Gathering the Necessary Materials

Before starting the repair process, ensure you have the following items:
• Padded Dash Filler
• Cream hardener
• Sandpaper (180 and 320 grit)
• Putty knife or spreader
• Cleaning solution (like isopropyl alcohol)
• Protective gloves
• Dust mask

Preparing the Damaged Area

1. Clean the cracked area thoroughly with a cleaning solution to remove any dirt or oils.

2. Use 180 grit sandpaper to gently sand around the crack, creating a slightly rough surface for better adhesion.

3. Wipe away any dust with a clean, dry cloth.

Applying the Padded Dash Filler

1. Mix a small amount of Padded Dash Filler with the cream hardener according to the product instructions.

2. Using a putty knife or spreader, apply the mixture to the cracked area, ensuring it fills the crack completely and extends slightly beyond the damaged zone.

3. Smooth the surface as much as possible, but don’t worry about perfection at this stage.

Allowing Proper Curing Time

Patience is key in this step. Allow the Padded Dash Filler to cure fully according to the manufacturer’s recommendations. This typically takes several hours, but it’s best to let it sit overnight for optimal results.

Sanding for a Smooth Finish

1. Once cured, start sanding the repaired area with 180 grit sandpaper to level the surface.

2. Gradually switch to 320 grit sandpaper for a finer finish, blending the repaired area with the surrounding dashboard.

3. Wipe away all dust with a tack cloth.

Finishing Touches

For a truly professional look, consider these additional steps:
• Apply a plastic primer to the repaired area.
• Use a color-matched paint or dashboard restoration product to blend the repair with the rest of the dashboard.
• Finish with a clear coat for added protection and sheen.
