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.
