Safety Precautions

Fiberglass dust can be harmful to your health, so it’s important to take the following safety precautions:

• Wear disposable gloves and safety glasses.
• Work in a well-ventilated area.
• Avoid breathing in fiberglass dust.
• Wash your hands thoroughly after working with fiberglass.

Step-by-Step Instructions

1. Prepare the Work Area

Start by preparing the work area. This involves cleaning the area around the damaged area and masking off any areas that you don’t want to get fiberglass on.

2. Clean the Damaged Area

Next, clean the damaged area with acetone. This will remove any dirt, grease, or wax that could interfere with the repair.

3. Sand the Damaged Area

Once the damaged area is clean, sand it with sandpaper. This will create a rough surface that will help the fiberglass resin adhere.

4. Mix the Fiberglass Resin

Mix the fiberglass resin according to the manufacturer’s instructions. Be sure to wear gloves and safety glasses when mixing the resin.

5. Apply the Fiberglass Resin

Apply the fiberglass resin to the damaged area using a paintbrush. Be sure to work the resin into the cracks and crevices.

6. Allow the Resin to Cure

Allow the resin to cure for the amount of time specified in the manufacturer’s instructions.

7. Sand the Repaired Area

Once the resin has cured, sand the repaired area until it is smooth. Be sure to use a sanding block to avoid damaging the fiberglass.

8. Apply Primer

Apply primer to the repaired area. This will help to protect the fiberglass from the elements and prepare it for paint.

9. Apply Automotive Paint

Once the primer has dried, apply automotive paint to the repaired area. Be sure to use multiple coats of paint and allow each coat to dry completely before applying the next.

10. Wax and Polish the Repaired Area

Once the paint has dried, wax and polish the repaired area to protect it and give it a glossy finish.
