Understanding Lacquer and Its Polishing Needs
Lacquer, a clear or colored resin-based coating, was widely used on cars in the early 1900s to the 1960s. Unlike modern paints, lacquer does not contain isocyanates, giving it a characteristically softer and more fragile composition. Due to its delicate nature, lacquer requires special care and specific polishing techniques to avoid damage.
Essential Materials for Lacquer Polishing
Gathering the right tools and supplies is the first step towards successful lacquer polishing. Here’s what you’ll need:
- Polishing Machine: A random orbital polisher is recommended for polishing lacquer, as it provides controlled and even pressure distribution, reducing the risk of swirls.
- Polishing Pads: Use only pads specifically designed for lacquer polishing, as abrasive pads can scratch the surface. Foam pads in varying grades (light cutting, polishing, and finishing) are essential.
- Polishing Compound: Choose a cutting compound for removing deep scratches and imperfections, a polishing compound for removing swirls and minor scratches, and a finishing compound for restoring maximum gloss.
- Microfiber Cloths: These soft and lint-free cloths are ideal for removing polishing residue and applying finishing touches.
- Paint Inspection Light: This specialized light source helps detect swirls, scratches, and imperfections, ensuring a thorough polishing job.
Safety Precautions for Lacquer Polishing
Before you begin, it’s important to take safety precautions to protect yourself and your car:
- Wear gloves, eye protection, and a mask to avoid contact with chemicals and airborne dust.
- Ensure adequate ventilation in your work area to prevent inhaling harmful fumes.
- Clean the car thoroughly to remove dirt and debris that could scratch the surface during polishing.
- Test the polish on an inconspicuous area first to check for compatibility and desired results.

Step-by-Step Lacquer Polishing Process
Now, let’s dive into the detailed polishing process:
-
Prepare the Surface: Thoroughly wash and dry the car to remove any contaminants. Use a clay bar to eliminate surface imperfections like tar and embedded dirt.
-
Choose the Right Pad and Compound: Start with a light cutting compound and a light cutting pad to remove scratches and imperfections. Gradually switch to a polishing compound and pad, and finally a finishing compound and pad for increased gloss.
-
Apply the Compound to the Pad: Apply a small amount of polishing compound to the foam pad. Avoid excessive compound, as it can lead to streaking.
-
Set the Polisher to the Correct Speed: For lacquer polishing, generally use a low to medium speed setting on your polisher. Avoid applying excessive pressure, as this can damage the paint.
-
Start Polishing: Begin polishing on a small test area to ensure the desired results. Apply light, even pressure and move the polisher in small, overlapping circles. Keep the pad flat against the surface to ensure uniform polishing.
-
Inspect the Results: Use the paint inspection light to check for any scratches, swirls, or imperfections. If necessary, adjust the polishing compound or pad combination to achieve the desired results.
-
Remove Residue: After polishing, wipe off any polishing residue using clean microfiber cloths. Ensure no compound is left behind, as it can attract dirt and affect the final finish.
-
Repeat for the Entire Surface: Continue polishing the entire surface of the car, section by section, following the same steps above.
-
Apply a Protective Layer: Once the polishing is complete, apply a wax or sealant to protect the paint surface and maintain the restored shine.
Maintaining Your Polished Lacquer Paint
To preserve the results of your polishing efforts and keep your lacquer paint looking its best, follow these maintenance tips:
- Wash your car regularly using a gentle car wash soap and a soft mitt.
- Avoid using harsh chemicals or detergents that can damage the paint.
- Wax or seal your car every few months to protect the paint from UV rays and environmental elements.
- If you notice any scratches or imperfections, touch up the area promptly using a compatible polishing compound and pad.
