Causes of Blistering Paint

Step-by-Step Guide to Fixing Blistering Paint

1. Identify the Blistered Area:

Carefully inspect your car’s paint to locate the blistered areas. Mark them with a piece of masking tape for easy reference.

2. Sand the Blistered Paint:

Using 120-grit sandpaper, gently sand the blistered areas until the paint is removed, exposing the bare metal. Smooth out the edges of the sanded area.

3. Clean the Surface:

Wipe down the sanded area with a tack cloth to remove any dust or debris. Next, apply paint thinner to a clean cloth and wipe the surface to remove any remaining oils or dirt.

4. Apply Primer:

Apply a thin coat of primer to the sanded area. This will create a barrier between the bare metal and the new paint. Allow the primer to dry completely.

5. Fill Blisters (Optional):

If any blisters remain after sanding, use a putty knife to apply a small amount of auto body filler to the area. Scrape off any excess filler and allow it to dry.

6. Sand the Filler (Optional):

Once the filler is dry, sand it with 320-grit sandpaper until it is smooth and level with the surrounding paint.

7. Apply Paint:

Using a paintbrush or spray gun, apply two thin coats of automotive paint to the repaired area. Allow each coat to dry completely before applying the next.

8. Clear Coat:

After the paint is dry, apply two coats of clear coat to protect the paint and give it a glossy finish. Allow the clear coat to dry completely.

9. Sand and Polish (Optional):

For a professional-looking finish, use 1200-grit sandpaper to lightly sand the clear coat surface. Then, apply a polishing compound and buff the area to restore its shine.

Tips for Preventing Blistering Paint

• Properly prepare the surface before painting.
• Use compatible paints and primers.
• Allow each coat of paint and primer to dry completely before applying the next.
• Protect the paint from moisture and sunlight.
