Materials You’ll Need

• Masking tape
• Scissors
• Paintbrushes
• Disposable gloves
• Protective eyewear

Step-by-Step Guide

Before you begin, make sure your door panels are clean and free of any dirt or debris. You don’t want anything to interfere with the fiberglass bonding to the panel.

Step 1: Cut the Fiberglass Mat

Using scissors, cut the fiberglass mat to the size and shape of your door panel. Make sure the mat is slightly larger than the panel to allow for trimming later.

Step 2: Mix the Fiberglass Resin

Put on your disposable gloves and protective eyewear. In a well-ventilated area, mix the fiberglass resin according to the manufacturer’s instructions. Use a paintbrush to apply a thin layer of resin to the door panel.

Step 3: Apply the Fiberglass Mat

Place the fiberglass mat on top of the resin-coated door panel. Use the paintbrush to apply another layer of resin on top of the mat, making sure it’s completely saturated. Smooth out any air bubbles or wrinkles as you go.

Step 4: Wait for the Resin to Dry

Let the resin dry completely. This can take anywhere from 30 minutes to 2 hours, depending on the temperature and humidity of your workspace.

Step 5: Sand the Fiberglass

Once the resin is dry, use 80-grit sandpaper to sand the surface of the fiberglass until it’s smooth and even. Then, use 120-grit sandpaper to smooth out any rough spots. Finish with 220-grit sandpaper to give the fiberglass a polished look.

Step 6: Apply Body Filler

If there are any gaps or uneven areas on the surface of the fiberglass, use body filler to fill them in. Apply the body filler with a putty knife and let it dry completely.

Step 7: Sand the Body Filler

Once the body filler is dry, use 80-grit sandpaper to sand it down until it’s smooth and even. Then, use 120-grit sandpaper to smooth out any rough spots. Finish with 220-grit sandpaper to give the body filler a polished look.

Step 8: Apply Paint or Vinyl Wrap

Now that your door panel is smooth and even, you can paint it or apply a vinyl wrap to give it a custom look. Use masking tape to protect any areas you don’t want to paint or wrap.

Step 9: Reinstall the Door Panel

Once the paint or vinyl wrap is dry, reinstall the door panel onto your car. Enjoy your new custom look!
