How to Blend Paint on a Body Panel of a Car

Blending paint is a technique used to create a smooth transition between two different colors or shades of paint. This is often necessary when repairing a damaged body panel, or when changing the color of a car. Blending paint can be a challenging task, but it can be done with a little practice.

Materials You Will Need

• Automotive paint in the desired color
• Automotive clear coat
• Mixing cups
• Stir sticks
• Spray gun
• Air compressor
• Masking tape
• Sandpaper
• Polishing compound

Step 1: Prepare the Surface

1. Wash and dry the body panel thoroughly.
2. Sand the damaged area with 320-grit sandpaper to remove any rust or imperfections.
3. Mask off the surrounding areas with masking tape.

Step 2: Mix the Paint

1. Pour a small amount of automotive paint into a mixing cup.
2. Add a few drops of clear coat to the paint and stir thoroughly.
3. Continue adding clear coat until the paint is the desired consistency.

Step 3: Apply the Paint

1. Hold the spray gun about 12 inches away from the body panel.
2. Start spraying at the edge of the damaged area and work your way towards the center.
3. Overlap each pass by about 50%.
4. Continue spraying until the damaged area is completely covered.

Step 4: Blend the Paint

1. Once the paint is dry, sand the edges of the blended area with 400-grit sandpaper.
2. Apply a second coat of paint to the blended area.
3. Sand the blended area again with 600-grit sandpaper.
4. Apply a third coat of paint to the blended area.

Step 5: Clear Coat

1. Once the paint is dry, apply a coat of clear coat to the blended area.
2. Allow the clear coat to dry for 24 hours.
3. Sand the clear coat with 800-grit sandpaper.
4. Polish the clear coat with a polishing compound.

Tips

• Use a spray gun with a fine nozzle to achieve a smooth finish.
• Do not apply the paint too thickly, as this will make it difficult to blend.
• Overlap each pass by about 50% to ensure a smooth transition.
• Be patient and take your time. Blending paint is a time-consuming process, but it is worth it to achieve a professional-looking finish.
