Gold and silver leaf applications add a stunning, classic finish to vehicles. Whether you’re working on a custom job or restoring a vintage car, the process requires precision and care. In this guide, we’ll walk you through the steps of applying gold or silver leaf, creating an engine-turned finish, and adding pinstripe outlines to complete the look.

1. Preparing the Surface
Before you begin, ensure the surface is clean and free of dust, grease, or oils. It’s crucial to have a smooth, prepared area to ensure proper adhesion. If you are working on a painted surface, make sure the paint has cured fully.
Pro Tip: Tape off the areas around your design to avoid messes and maintain crisp edges when applying leafing.
2. Applying the Adhesive (Size)
The next step is to apply adhesive, commonly known as “size.” There are different types, including oil-based and water-based sizes, with oil-based being ideal for automotive applications due to its durability. Using a fine brush, apply a thin and even layer of size to the area where the leaf will go. Allow it to sit until it becomes tacky, which usually takes 15 to 30 minutes depending on humidity levels.
For the best results, the size should feel sticky but not transfer to your skin when touched lightly.
3. Laying the Gold or Silver Leaf
Once the size is tacky, carefully lay sheets of gold or silver leaf over the surface. Gold and silver leaf are incredibly delicate, so handle them gently, using tissue or wax paper to transfer the sheets onto the adhesive. Tap the leaf lightly with the tissue to ensure it sticks fully.
After covering the entire area, use a soft makeup brush to remove the excess leaf, brushing gently to avoid tearing the applied material.
4. Burnishing and Sealing
Burnishing the leaf will smooth out any wrinkles and give the design a polished look. Use a soft cloth to burnish the leaf and remove any remaining excess pieces. Once burnished, it’s important to seal the leaf, especially if you’re using imitation gold or silver, which can tarnish over time. A clear coat of varnish or automotive clear coat will protect the leaf from damage and environmental exposure.
5. Engine Turning (Optional)
Engine turning adds a unique, swirling effect to your gold or silver leaf, often used on custom work. To achieve this effect, you’ll need a burnishing tool. A simple tool can be made by wrapping velvet around a cotton ball and securing it to a handle, like a brush. Press and twist the tool into the leaf, creating circular patterns. Start at one edge and overlap the circles to create a continuous effect.
This technique gives the leaf a reflective, textured appearance that catches light differently, adding depth to the finish.
6. Adding Pinstripe Outlines
To finish off the design, you can add pinstripe outlines around the leafed area. Use a small brush (00 or 000 size) for the best control and precision. Common colors for pinstriping include black, red, or darker shades of gold or silver to complement the leafing.
If you prefer a mechanical approach, a Beugler striping tool can be used for uniform pinstripes. Let the pinstripe paint dry completely before applying a protective clear coat over the entire design.
Final Steps
Once the leaf, engine turning, and pinstriping are complete, apply a protective clear coat to seal the entire design. Use two light coats followed by a heavier one, allowing each coat to cure before adding the next. This will protect the leaf from fading or damage, ensuring it remains vibrant for years to come.
Conclusion
Gold and silver leaf application, engine turning, and pinstriping are advanced techniques that elevate the look of any vehicle. With the right tools and a bit of patience, you can achieve a stunning, long-lasting finish that sets your project apart.
