We give rust the old 1-2

Vermont roads are brutal on vehicles. Salt, moisture, and freeze-thaw cycles go after every bit of exposed metal. We stop rust before it starts with professional Waxoyl undercoating that protects for the life of your vehicle.

Why Byrnes

It’s Us
or Rust.

Vermont winters are relentless. Byrnes Rustproofing Center has been protecting vehicles across Rutland County for over 15 years, using professional-grade Waxoyl products that penetrate deep and protect permanently.

Unlike cheaper treatments that dry out and crack, Waxoyl’s advanced chemistry never dries. It sticks forever, heals scratches, and even kills existing surface rust. One application. Lifetime protection.

What We Offer

Our Services

Professional Waxoyl undercoating and rustproofing applied to vehicle undercarriage in Vermont
Undercoating & Rustproofing
Professional Waxoyl Hardwax applied to your undercarriage forms a permanent, flexible barrier that kills existing surface rust, never dries, and protects for the life of your vehicle. We also offer cavity protection that fogs internal door panels, rocker panels, and frame rails. Minor touch-up work available alongside your rustproofing service.
Spray-in truck bed liner application at Byrnes Rustproofing Center North Clarendon Vermont
Spray-In Bed Liners
Bullet Liner spray-in bed liner is applied directly and permanently to your truck bed, protecting against scratches, dents, and corrosion far better than any drop-in liner. The result is a tough, textured surface that bonds to the metal and lasts the life of the truck.

How We Do It

A Rigorous 3-Step
Undercoating Process

No shortcuts, no spraying over dirt. Every vehicle goes through the same three steps, and none get skipped. Click through to see what happens at each stage.

Pressure Wash & Dry

Waxoyl needs clean metal to grab onto. Your vehicle is fully pressure washed, undercarriage included, then left to dry overnight before any product goes on.

  • Full undercarriage wash
  • Dried overnight
  • Nothing sprayed over dirt or water

From the Owner

About Us

As the owner, I have always valued making things last, and that extended to the vehicles I owned. It was obvious to me at a very young age that the number one enemy in the lifetime of any vehicle would be corrosion, or simply said, rusting out.

About 15 years ago I started a small rustproofing shop using Waxoyl products. Through our experience, we developed a process we feel so confident in that we offer a lifetime guarantee for vehicles that are brand new when we rustproof them.

I currently own a 1966 Ford F-100 Pickup that I have had for 45 years. Many folks ask how long we can make their car last, and I suggest: “Let’s shoot for 50 years!”

— Shawn Byrne, Owner
Authorized Waxoyl Dealer Bullet Liner Installer

Byrnes Rustproofing Center is located at 33 Pleasant Drive in the village of North Clarendon, Vermont, conveniently situated at our dedicated rustproofing shop serving all of Rutland County and beyond.

We use Waxoyl Hardwax for undercarriage rust protection and Waxoyl 120-4 for internal cavity protection. Unlike conventional rustproofing products that coat the surface, dry out, crack, and expose rust over time, Waxoyl’s advanced chemistry actively kills existing surface rust, never dries, sticks permanently, and even heals minor scratches.

We also carry products from NHOU and are an authorized Bullet Liner spray-in bed liner installer. We also offer touch-up work, giving you a complete vehicle protection solution under one roof.

Common Questions

Before You Book

How long will you need my vehicle?

Plan on two days. Your vehicle is washed and left to dry overnight, then the Waxoyl goes on the following day.

Can I get it done in the middle of winter?

Yes. We work year-round, in any season and any weather.

Will Waxoyl dry out and crack like other undercoatings?

No. Waxoyl never dries. It stays flexible and sticks permanently, and it kills existing surface rust and even heals minor scratches.

My vehicle isn’t brand new. Is it still guaranteed?

Every vehicle we rustproof is covered by our workmanship guarantee. If it leaves our store without meeting our undercoating service standards, we will fix it. The lifetime guarantee applies to vehicles that are brand new when we rustproof them.

Do you do anything besides undercoating?

We also do cavity protection, Bullet Liner spray-in bed liners, and touch-up work. You can get all of it done under one roof.

"I had both my camper van and my car undercoated by Shawn and could not be happier with the experience. He was incredibly communicative and professional, and I truly felt like my vehicles were in great hands. I drove two hours to have the work done and it was absolutely worth it. I highly recommend Shawn to anyone looking for high-quality undercoating."
