Here are the steps you’ll need to take to sand…

Preparation Steps

Clean the Surface

Gather Cleaning Supplies: Collect a soft cloth, soap, water, and a bucket. These items are crucial for ensuring a clean surface before you begin the sanding process.

Prepare Soap Solution: Pour water into a bucket until it’s about halfway full. Add a generous squirt of car wash soap or a mild dish soap, and stir the solution until it forms a soapy mixture.

Wash the Area: Fold your soft cloth into a square, then dip it into the soapy water. Gently scrub the surface where the clear coat is peeling, using circular motions. Your goal here is to remove all contaminants like dirt, grease, and any loose flakes of clear coat that might interfere with the sanding process.

Rinse and Dry: Using clean water, rinse off all the soap from the area you just cleaned. Take another soft cloth and dry the surface completely. A dry surface ensures that your sandpaper won’t get clogged during sanding, allowing for a more effective and smooth result.

Mask Adjacent Areas

Identify Areas to Mask: Observe the area surrounding the damaged clear coat. Identify regions like trim, headlights, or any other adjacent areas that you want to protect from the sanding process.

Apply Masking Tape: Cut several strips of automotive masking tape and apply them carefully around the area you’re planning to sand. Press down firmly to ensure that the tape adheres well to the surface, preventing any sanding residue or activity from affecting unintended areas.

Sanding the Peeling Clear Coat

Start with 400-Grit Sandpaper

Position the Sandpaper: Hold the 400-grit sandpaper so that it’s comfortable in your dominant hand. Place it flat against the area where the clear coat is peeling.

Light Sanding: With a gentle, circular motion, begin sanding the surface. It’s important to exercise caution to avoid damaging the paint underneath the clear coat.

Check the Surface: Periodically stop sanding to examine the surface. If the peeling clear coat has been effectively removed, you can proceed to the next step. If not, continue with your light sanding.

Move to 800-Grit

Switch Sandpaper: Set aside the 400-grit sandpaper and replace it with an 800-grit sheet.

Intermediate Sanding: Continue with the circular motion, but this time with the 800-grit sandpaper. This will further smooth out any rough edges left by the initial sanding, preparing the surface for the final stage.

Finish with 2000-Grit

Last Sandpaper Switch: Now it’s time to switch to the finest sandpaper—2000-grit.

Final Sanding: Sand the area for the last time to achieve the smoothest finish possible. This fine sanding is critical for ensuring that any new clear coat or wax will adhere properly.

Finishing Touches

Clean the Sanded Area

Remove Residue: After you’ve completed the sanding process, take a new soft cloth and gently wipe away any remaining sanding dust or residue. If needed, use a mild soap solution to make sure all residues are completely removed.

Rinse and Dry: Rinse the area with clean water to remove any lingering soap. Use a soft cloth to dry the surface completely.


Check the Surface: Examine the area closely to ensure it looks smooth and is free from peeling clear coat.

Decide on Next Steps: If you are satisfied with the appearance, you can consider it a job well done and proceed to reapply a new clear coat or wax for added protection and shine. If the area still requires work, you may need to revisit some of the sanding steps for further refinement.
