If you’ve been waxing your fiberglass trailer a few times a year, you might think you’re doing all you can to protect your gelcoat finish. But ceramic coatings have become the go-to solution for serious long-term protection—and for good reason.
At CGI Detailing, we specialize in protecting fiberglass travel trailers across the nation with our home base being Middle, Tennessee. We protect each trailer with Glidecoat Ceramic Coating, a ceramic coating specifically designed for gelcoat surfaces. In this post, we’ll break down the differences between wax and ceramic coating so you can make the best choice for your trailer—and your wallet.
Wax for Fiberglass: What It Does (and Doesn’t Do)
Waxing your trailer does offer some benefits. It enhances shine, provides a little UV protection, and helps water bead off the surface. But the protection is temporary—especially on porous gelcoat.
What you might not realize is:
Most waxes wear off in 1–3 months (Wax begins to melt at 110 degrees Fahrenheit)
Frequent reapplication is needed
They break down faster when trailers are stored outdoors
Plus, waxes don't bond with the surface—they just sit on top. That means every time it rains or you wash the trailer, you’re removing some of that protection.
Ceramic Coating: Why It’s a Step Above
Ceramic coatings chemically bond to the trailer’s gelcoat, creating a hard, protective layer that resists UV rays, dirt, water spots, and oxidation. Instead of needing constant reapplication, ceramic coatings last up to 2+ years with proper care.
Ceramic coating also:
Repels dirt, bugs, and road grime
Makes washing dramatically easier
Preserves shine without streaking or haze
Reduces the risk of long-term gelcoat oxidation
And unlike wax, it won’t melt away in summer heat or wash off in a storm. So the more you wash, the better!
Wax vs Ceramic: Head-to-Head Comparison
Protectant | Wax | Ceramic Coating (Glidecoat) |
Lifespan | 1–3 months | Up to 2 years |
UV Protection | Low | High |
Oxidation Resistance | Minimal | Excellent |
Shine & Gloss | Good (fades quickly) | Deep, long-lasting |
Maintenance | Frequent reapplication | Monthly wash |
Bonds with Gelcoat | No | Yes |
Ideal for Outdoor Storage? | No | Yes |
What’s the Cost Difference?
Here’s where the long-term value really stands out:
🧼 Waxing (if done by a professional)
$300-$800 per application (depending on trailer size)
Recommended 4 applications per year if stored outside
2-Year Total: $2,400–$6,400+
🛡️ Ceramic Coating (Glidecoat Ceramic Coating)
One-time application starting around $1,700-$3,400 -(depending on trailer size and gelcoat condition)
No need to reapply for 24 months
2-Year Total: $1,700-$3,400 One service + easier maintenance
Ceramic coating is an upfront investment that saves you time, energy, and long-term detailing costs. And it helps preserve the value of your trailer. If the trailer is properly maintained over the course of those 2 years, the reapplication process can be significantly cheaper.
🧼 Waxing (if done by consumer)
$50-$150 per application (depending on trailer size)
Recommended 4 applications per year if stored outside
2-Year Total: $400–$1,200+
🛡️ Ceramic Coating (DIY: Glidecoat Ceramic Coating)
One-time application starting around $500 -(depending on trailer size and gelcoat condition)
No need to reapply for 24 months
2-Year Total: $500 One service + easier maintenance
If your fiberglass trailer is properly maintained over the course of those 2 years, application of the ceramic coating will be much easier and less labor intensive going forward saving you time, energy and money.
Why We Use Glidecoat Ceramic Coatings

This isn’t just a harder coating—it's more chemical resistant, more durable, and better at blocking UV making it the perfect ceramic coating for fiberglass trailers.
Already Maintaining Your Trailer? Upgrade It
If you’ve been waxing your trailer regularly, you’re clearly committed to caring for it—and that’s a great start. But if you’re ready to upgrade your protection, reduce maintenance, and keep that fiberglass shine year-round, ceramic coating is the best move.
