Preparing The Surface
Preparing the surface is the first step to airbrushing fake body side molding. This step ensures the paint sticks well and looks smooth. Proper preparation helps avoid paint peeling or bubbling later. Taking time here saves effort in the long run.
Cleaning And Sanding
Start by cleaning the molding with soap and water. Remove all dirt, grease, and dust. Use a cloth to wipe it dry.
Next, sand the surface lightly. Use fine-grit sandpaper for this job. Sanding creates a rough texture for the paint to hold on.
After sanding, wipe the surface with a clean, dry cloth. This removes any leftover dust particles.
Masking Surrounding Areas
Protect areas around the molding with masking tape. Cover parts that should not get paint on them.
Use paper or plastic sheets to shield larger sections. Secure the edges of the tape tightly to avoid paint leaks.
Masking keeps the work clean and professional. It saves time on cleanup after airbrushing.
Choosing The Right Paint
Choosing the right paint is key for airbrushing a fake body side molding. The paint must stick well and look smooth. It should also match the car’s color perfectly. Picking the right paint helps the molding blend in and look natural. This section explains how to select the best paint for your project.
Selecting Paint Types
Use paint made for plastic surfaces. These paints stick better and last longer. Acrylic paints are a good choice. They dry fast and give a smooth finish. Urethane paints are tougher and resist chips. Avoid enamel paints. They can crack on plastic parts.
Look for paints labeled as automotive or plastic paints. These have the right chemicals for molding. Also, check if the paint works with your airbrush system. Thin paints spray easier and give even coverage.
Matching Colors
Match the paint color to your car’s original shade. Use the car’s paint code found on the door or frame. This code tells you the exact color formula. Buy a paint sample or mix colors to get a perfect match.
Test the color on a small area first. Let it dry and compare it under natural light. The right match makes the molding look like part of the car. Poor color matching stands out and looks fake.
Setting Up The Airbrush
Setting up the airbrush correctly is key to painting a fake body side molding. Proper setup ensures smooth paint flow and even coverage. Take your time with this step for the best results.
Equipment And Tools Needed
Gather all necessary tools before starting. You need an airbrush, air compressor, paint cup, and cleaning supplies. Also, prepare masking tape and protective gloves. Have a spray booth or well-ventilated area ready.
Adjusting Air Pressure
Set the air compressor to the right pressure. For side moldings, 15 to 25 PSI works well. Too high pressure causes paint splatter. Too low pressure leads to uneven spray. Adjust slowly and test on scrap material.

Applying The Base Coat
Applying the base coat is a key step in airbrushing a fake body side molding. This layer sets the tone for the final finish. It helps the paint stick better and gives the molding a smooth look. Taking your time with the base coat ensures a clean and even surface for the next paint layers.
Techniques For Smooth Coverage
Start by cleaning the molding to remove dust and oils. Hold the airbrush about 6 to 8 inches away from the surface. Use steady, even strokes from side to side. Keep the airbrush moving to avoid paint buildup. Apply thin layers rather than one thick coat. Let each layer dry slightly before adding the next.
Drying Times
Allow the base coat to dry for about 10 to 15 minutes between layers. This helps prevent runs and drips. Avoid rushing the process. If the paint feels tacky, wait a little longer. Proper drying improves paint adhesion and finish quality. Follow the paint manufacturer’s instructions for best results.
Adding Details And Layers
Adding details and layers is key to making your fake body side molding look real. This process helps create depth and brings out the shape. It makes the molding stand out from the car surface. You will use different colors and techniques to build up the look slowly. Patience is important here. Each layer adds more life to the molding.
Creating Shadows And Highlights
Shadows and highlights give the molding its three-dimensional look. Use darker shades to create shadows where the molding curves inward. Light colors should go on areas that catch light. Spray gently to blend the colors smoothly. This contrast makes the molding look like it has real depth. Think about where natural light would hit the molding on a real car. Mimic that with your airbrush for the best effect.
Layering For Depth
Apply colors in thin layers to build depth. Start with a base color that matches the car’s paint. Add darker colors on top for shadows. Then, add lighter colors for highlights. Each layer should dry before adding the next. This prevents the paint from running or mixing. Layering helps the molding look natural and detailed. It gives the fake molding a solid, real feel.

Finishing Touches
Finishing touches bring the airbrushed molding to life. These steps protect your work and reveal the final look. Take your time to do them right. They make a big difference in durability and shine.
Clear Coating
Clear coating seals the paint and adds shine. Use a spray clear coat made for automotive parts. Hold the can or spray gun about 6 to 8 inches away. Apply light, even coats to avoid runs. Let each coat dry before adding the next. Two to three coats usually work best. This layer protects against chips and fading. It also makes the molding look smooth and glossy.
Removing Masking Tape
Remove masking tape carefully after the clear coat dries. Pull the tape slowly at a sharp angle. This prevents peeling or lifting the paint. Remove tape before the clear coat is fully hard but dry enough. This timing helps avoid sharp edges or cracks. Check edges for any touch-ups after tape removal. Smooth out small mistakes with a fine brush or sandpaper.
Common Mistakes To Avoid
Airbrushing fake body side molding can be tricky. Mistakes may ruin the finish or cause extra work. Knowing common mistakes helps avoid problems and saves time. Follow these tips to keep your work clean and smooth.
Not Preparing The Surface Properly
Failing to clean or sand the molding leads to poor paint adhesion. Dirt, grease, or rough spots cause uneven paint layers. Always wash and lightly sand the molding before airbrushing.
Using The Wrong Paint Type
Choosing paint not made for plastic or automotive use causes peeling or cracking. Use paint designed for fake body moldings or plastics. This ensures strong and flexible coverage.
Applying Paint Too Thickly
Heavy coats cause drips, runs, and uneven texture. Apply several thin layers instead. Let each layer dry before the next. Thin coats build smooth color without defects.
Ignoring Proper Airbrush Settings
Wrong air pressure or nozzle size affects spray pattern. This leads to blotchy or splattered paint. Adjust airbrush settings for fine, even mist on small moldings.
Skipping Masking And Protection
Not masking nearby areas causes overspray and mess. Cover parts around molding with tape and paper. Protect your workspace to keep paint only where it belongs.
Maintenance Tips
Maintaining your airbrush and the painted surface of your fake body side molding ensures long-lasting results. Proper care keeps the colors bright and prevents damage. Regular attention to both tools and paint helps you save money and effort in the future.
Cleaning The Airbrush
Clean your airbrush immediately after use. Remove leftover paint to avoid clogs. Use the right cleaning solution based on your paint type. Flush the airbrush with water or cleaner until it runs clear. Wipe all parts gently with a soft cloth. Take care not to damage small pieces. Regular cleaning keeps the airbrush working smoothly every time.
Preserving The Painted Surface
Protect the painted molding from dirt and scratches. Wash it gently with mild soap and water. Avoid harsh chemicals or abrasive materials. Dry the surface with a soft cloth to prevent water spots. Park your vehicle in shade to reduce sun damage. Apply a clear coat or sealant for extra protection. Follow these steps to keep your paint fresh and vibrant longer.
