How do you repair orange pealling in auto painting?

Orange peel, also called "fish eye", is a common defect in auto painting that occurs when the paint dries too quickly, resulting in a rough, bumpy surface. Here's how to repair it:

Materials Needed:

- Sandpaper (1500 grit and 2000 grit)

- Sanding block or orbital sander

- Tack cloth

- Polishing compound

- Polishing pad or buffer

- Water

Step 1: Preparation

- Start by washing and drying the car to remove any dirt or contaminants.

Step 2: Sanding

- Sand affected areas using 1500 grit sandpaper. Avoid sanding into the original car paint.

- Use a sanding block or orbital sander for even pressure.

- Wet sand by spraying water onto the paint surface to help lubricate the sandpaper and prevent scratches.

Step 3: Repeat Sanding

- Clean the area with a tack cloth.

- Repeat the sanding process with 2000 grit sandpaper to smooth the surface further.

Step 4: Clean and Dry

- Thoroughly clean the area again to remove any sanding dust.

- Let the area dry completely.

Step 5: Apply Polishing Compound

- Apply a small amount of polishing compound to the affected area.

- Use a polishing pad or buffer and work with a circular motion to buff the surface.

Step 6: Repeat Polishing

- Continue polishing until the orange peel effect is removed, gradually increasing the speed of the buffer as you go.

- Check the progress under bright lighting.

Step 7: Final Clean-up

- Wipe off any excess polishing compound with a clean microfiber cloth.

- Inspect the area to ensure the orange peel is gone.

- Wax or seal the area to protect the newly polished surface.

Tips:

- Always test the sanding and polishing process on an inconspicuous area first.

- Be patient and apply minimal pressure when sanding to avoid damaging the paint further.

- Use slow, consistent strokes when buffing.

- Protect the surrounding areas from sanding and polishing dust.

- For deep orange peel, you might need to reapply the base coat and clear coat.
