If you’re an RV enthusiast, you know that maintaining the exterior of your vehicle is essential to preserving its value and ensuring a safe and enjoyable travel experience. Learning how to repair RV fiberglass exterior damage yourself can save you time and money, while giving you a sense of accomplishment. This guide will walk you through the steps to repair fiberglass damage on your RV, discuss the tools and materials needed, and offer tips to prevent future damage. Whether you're an experienced traveler or new to the world of RVs, this article will help you keep your vehicle in top shape.

Understanding Fiberglass Damage

Fiberglass is a common material for RV exteriors because it's durable and lightweight. However, it can still suffer from scratches, cracks, and holes due to road debris, weather conditions, or accidental impacts. Regular RV maintenance services are essential to catch and repair minor damage before it becomes a major issue.

Tools and Materials Needed

Before you start the repair process, gather the following tools and materials:

  • fiberglass repair kit;
  • sandpaper (various grits);
  • clean cloth;
  • acetone or a similar solvent;
  • protective gloves and mask;
  • putty knife or applicator;
  • paint and paintbrush (optional).

Step-by-Step Repair Process

Clean the damaged area

Start by washing the damaged area with soap and water, then wipe down with acetone to remove grease or residue. This creates a clean surface for the products to adhere to.

Sand the area

Use soft sandpaper to smooth the damaged area. This helps the fiberglass resin bond more effectively. Be sure to sand a slightly larger area than the damage itself.

Prepare the fiberglass repair kit

Follow the instructions on your fiberglass repair kit to mix the resin and hardener. Wear protective gloves and a mask to avoid chemical exposure.

Apply the Resin

Use a putty knife or applicator to spread the mixed resin over the damaged area. If the damage is a hole, apply a piece of fiberglass cloth or mat over the resin and then apply another layer of resin on top.

Smooth the Surface

After applying the resin, use the putty knife to smooth out the surface. This step is crucial for achieving a professional-looking repair.

Allow to Cure

Let the resin cure according to the manufacturer's instructions. This usually takes several hours, so be patient.

Sand and Paint

Once the resin has cured, sand the area with fine-grit sandpaper to achieve a smooth finish. If desired, paint the repaired area to match the rest of your RV's exterior.

Tips for Preventing Future Damage

While knowing how to repair RV fiberglass exterior damage is invaluable, preventing damage in the first place is even better. Consider these tips:

Avoiding Hail Damage

Consider investing in Titan Spray-On Roof Lining, which provides a durable layer of protection against hail and other harsh weather conditions. This upgrade is highly recommended for those frequently traveling in areas prone to severe weather.

Regular Inspections

Check your RV regularly, especially after a long trip. Finding minor issues early can prevent costly repairs.

Store Properly

When not in use, store your RV in a safe place to protect it from the elements. If indoor storage facilities are not available, consider using an RV cover.
