The Ultimate Guide to Maintaining a Fiberglass Travel Trailer

By CGI Detailing – Professional Ceramic Coatings

Owning a fiberglass travel trailer is one of the best ways to explore the open road with comfort and style. From iconic brands like Casita, Scamp, Escape and Oliver, fiberglass trailers offer lightweight convenience and a sleek, aerodynamic look. But to keep that glossy shell in great condition for years to come, proper care is essential.

At CGI Detailing, we specialize in mobile detailing services for fiberglass RVs across Middle Tennessee. Whether you're prepping for your next trip or putting your trailer into storage, here's our expert guide to keeping it in top shape.

Why Fiberglass Maintenance Matters

Fiberglass trailers are typically coated in gelcoat—a protective, glossy layer that enhances appearance and shields against the elements. Over time, sun exposure, road grime, and oxidation can dull this finish, making your trailer look older than it is and even reducing resale value.

Regular maintenance not only keeps your trailer looking sharp but also:

• Prevents costly gelcoat repairs

• Maintains water resistance

• Reduces long-term damage from UV and environmental exposure

Step-by-Step Maintenance for Fiberglass Trailers

1. Wash Frequently with the Right Products

Use a pH-balanced RV soap (not household cleaners!) to safely lift away dirt, bug splatter, and road film. Avoid harsh detergents that strip wax or damage the gelcoat.

Pro Tip: CGI Detailing uses a ceramic infused, gelcoat-safe shampoo called Polymer Infused Soap that adds protection to the surface as you clean.

2. Use a Foam Cannon and Hand Wash with Microfiber

Gentle tools are key to preventing swirl marks or scratches. Avoid stiff brushes and abrasive pads.

3. Don’t Forget the Roof and Trim

The roof collects the most dirt and is the most impacted by the harmful UV rays. Many people skip it—but we never do. Keeping the roof clean reduces streaking and protects structural integrity.

4. Clay Bar Treatment for Contaminant Removal

At least once a year, a clay bar treatment helps lift embedded contaminants like tree sap and industrial fallout—things washing alone can’t remove.

5. Oxidation? Use a Fiberglass Restorer (Compound)

If your trailer is already dull or chalky, you may need to restore it. We recommend compounding / polishing your trailer with a gelcoat specific compound to remove oxidation before you protect it!

4. Apply a UV-Protective Wax or Sealant

Use a wax or ceramic sealant designed for fiberglass. These products enhance shine and create a hydrophobic layer that helps prevent water spots, oxidation, and fading.

How Often Should You Detail a Fiberglass Trailer?

• Basic Wash: Every 2–4 weeks during travel season

• Wax/Sealant: Every 2-3 months

• Full Detail (with oxidation removal): Once a year or as needed If you're storing your trailer, clean and protect it before it goes into storage to prevent buildup and oxidation.

For trailer owners looking for the highest level of protection, nothing beats ceramic coating. While waxes and sealants offer decent short-term defense, a true ceramic coating bonds to the gelcoat and delivers long-lasting, high-gloss performance.

At CGI Detailing, we recommend and apply Glidecoat ALPHA Graphene Ceramic Coating

—a premium, marine-grade ceramic coating formulated specifically for fiberglass and gelcoat surfaces. It provides 2+ years of protection, enhanced UV and chemical resistance, and a stunning, hydrophobic shine that keeps your trailer looking better, longer.

Whether you're prepping for a road trip or tucking your trailer away for the season, ceramic coating is the smartest way to preserve its value and appearance.
