Preparing the Area for Fiberglass Repair
Before you begin, gather your supplies: safety glasses, gloves, sandpaper (80-grit, 180-grit), masking tape, metal grinder or sandpaper, rust converter, fiberglass cloth, fiberglass resin, hardener, body filler, and primer. Start by cleaning the rusted area thoroughly with soap and water. Then, using 80-grit sandpaper or a metal grinder, remove all loose rust and paint around the affected area. This creates a clean surface for the fiberglass to adhere to. Next, apply a rust converter to the bare metal to neutralize any remaining rust and prevent future corrosion.
Applying the Fiberglass
Now, mix the fiberglass resin and hardener according to the manufacturer’s instructions. Apply a thin layer of resin to the prepared metal surface. Cut a piece of fiberglass cloth slightly larger than the repair area and place it over the wet resin. Using a brush or spreader, saturate the cloth with more resin, ensuring it conforms to the contours of the car body. Allow the resin to cure completely. This usually takes a few hours, but check the manufacturer’s guidelines for specific curing times.
Smoothing and Finishing
Once the resin has cured, use 180-grit sandpaper to smooth the fiberglass patch, feathering the edges into the surrounding paint. This blending process is crucial for a seamless repair. Next, apply a thin layer of body filler over the fiberglass patch to fill any remaining imperfections and create a smooth, even surface. After the body filler dries, sand it smooth with 180-grit sandpaper, then apply a coat of primer to prepare the area for painting.

Painting and Protecting the Repaired Area
Finally, paint the repaired area to match the rest of your car’s finish. You can use touch-up paint or have the entire panel professionally repainted for a seamless blend. Apply a clear coat to protect the paint and prevent future rust. For long-term protection, consider applying a rust inhibitor to the underside of the repaired area.
