How to Stop and Prevent Rust on Steel UTV Skid Plates

Skid plates are some of the hardest-working parts on a UTV. Every time you roll over rocks, logs, stumps, ruts, and trail debris, the skid plates take the pounding so your UTV’s engine, driveline, chassis, suspension, and belly pan don’t. They’re essential armor—and for many riders, nothing beats steel skid plates for impact resistance and long-term durability.

But unlike UHMW or aluminum skid plates, steel skid plates can rust. And once a skid plate’s coating is scratched or gouged, rust can move fast. Whether you’re riding in wet conditions, rocky terrain, or areas treated with winter road salt, that constant exposure can turn a strong steel plate into a weak, corroded one.

This guide explains UTV skid plate rust prevention, coating UTV skid plates effectively, and the best DIY method for steel skid plate rust protection using KBS products. You’ll learn how to stop existing rust, apply durable coatings, and protect your skid plates for years of off-road use.

What Are UTV Skid Plates Made of?

Most OEM and aftermarket UTV skid plates come in one of three materials:

Steel

• Most impact-resistant
• Best puncture resistance
• Typically, the most affordable
• Heavier than aluminum or UHMW
• Susceptible to rust when coatings are damaged

Aluminum

• Lighter than steel
• Doesn’t rust
• Can dent more easily
• Corrosion is usually minimal unless exposed to saltwater or road salt

UHMW (Ultra-High Molecular Weight Plastic)

• Doesn’t rust or corrode
• Extremely slick surface—slides well over obstacles
• Flexes rather than dents
• Not as stiff as steel

While aluminum and UHMW are attractive options, many riders prefer steel because it bends less, punctures less, and handles harsh impacts better. The downside? Rust is a constant threat.

Why Does Rust Form on Steel UTV Skid Plates?

Manufacturers finish steel skid plates with powder coat or other paints and coatings. They look great when new, but off-road use can chip, scratch, and gouge these finishes. Once bare metal is exposed to moisture, mud, oxygen, or salt, oxidation begins.

Because skid plates can stay wet and trap mud, they often rust faster than other parts of the UTV.

To solve this, you need a durable rustproof coating for UTV skid plates designed for extreme use—not just ordinary paint.

What Is the Best Coating for UTV Skid Plates and Why Use KBS Coatings?

For maximum durability and longevity, KBS provides a two-part DIY friendly coating system—KBS RustSeal followed by KBS Bed Liner or KBS Bed Renu

1. KBS RustSeal

A permanent rust-preventive coating that seals steel off from moisture, oxygen, and corrosives.

2. KBS Bed Liner

A thick, flexible, UV-stable protective coating that absorbs impacts and abrasion.

Together, these coatings create:

• High-impact rust coating for steel skid plates
• Long-lasting UTV skid plate corrosion protection
• Superior durability compared to standard paints
• A cost-effective DIY solution

3. KBS Bed Renu

• Aerosol spray version of KBS Bed Liner
• Offers the convenience of an aerosol spray
• Can be used to touch up KBS Bed Liner when needed

This system works on:

• Brand-new steel skid plates before installation
• Skid plates with scratches, chips, or worn powder coat
• Plates with surface rust
• Skid plates used in harsh weather, mud, or salty environments

Why Is KBS RustSeal Ideal for Steel Skid Plate Rust Protection?

KBS RustSeal is a 1K moisture-cured urethane formula engineered to stop rust permanently. It dries to a rock-hard but flexible finish that resists impacts and abrasion—perfect for steel UTV skid plates.

KBS RustSeal benefits include:

• Seals metal against moisture, oxygen, and salt
• Can be applied to bare metal or treated surface rust
• Flexes without cracking when the skid plate flexes
• Can be brushed, rolled, or sprayed
• Self-levels for a smooth finish

KBS RustSeal forms the first layer of protection. To maximize durability, you finish by applying KBS Bed Liner over it.

Why Add KBS Bed Liner Over KBS RustSeal?

While KBS RustSeal handles the job of stopping and preventing rust, KBS Bed Liner (or optionally - KBS Bed Renu

KBS Bed Liner is:

• Tough, flexible, and impact-resistant
• Great at absorbing hits from rocks and debris
• UV stable
• Resistant to abrasion caused by sand, gravel, and trail debris

Together, KBS RustSeal + KBS Bed Liner (or KBS Bed Renu

How Do You Prepare Steel UTV Skid Plates Before Coating?

Surface prep is a highly important step. KBS RustSeal bonds strongest when prep is done correctly.

Step 1: Remove Loose Rust, Paint, and Coating

Use one of the following:

• Wire brush
• 320-grit sandpaper
• Sandblasting

Your goal is to remove all loose coating, loose rust, and failing paint. KBS RustSeal needs a solid foundation for the strongest, most durable adhesion.

If some coating is still firmly adhered: Scuff it with 320-grit sandpaper to give RustSeal a tooth to grip.

How Do You Clean Skid Plates Before Applying KBS RustSeal?

Once loose rust and paint have been removed, and/or well adhered existing coatings have been scuffed, the surface must be completely cleaned with KBS Klean. This powerful degreaser and cleaner removes dirt, grease, and grime, without leaving adhesion-hindering residue.

Use KBS Klean as directed:

• Mix KBS Klean with warm water and scrub with a sponge or bristle brush
• Rinse and dry thoroughly
• Full instructions HERE

What’s the Next Step Before Applying RustSeal?

Before applying KBS RustSeal the metal needs to be treated with KBS RustBlast.

Why use KBS RustBlast?

KBS RustBlast:

• Penetrates and dissolves rust
• Neutralizes surface oxidation
• Etches metal for best adhesion of RustSeal

Do You Need KBS RustBlast Before Applying RustSeal?

Yes—unless the metal was sandblasted; KBS RustSeal can be directly applied to newly sandblasted metal surfaces that have been handled with gloved hands. No preparation other than blowing off loose dust is required.

How Do You Apply KBS RustBlast Properly?

• Spray on KBS RustBlast and keep wet for 30 minutes–2 hours depending on the amount of rust
• Scrub intermittently with a Scotch-Brite pad
• Rinse and dry thoroughly
• A whitish zinc-phosphate residue will remain; this prevents flash rust. Do not remove
• Full instructions HERE

Once dry, you’re ready to apply KBS RustSeal.

How Do You Apply KBS RustSeal to UTV Skid Plates?

• Choose your application method: Brushing, rolling, or spraying
• Optimal temperature: Apply between 55–82°F, avoiding rain or high humidity
• Mix thoroughly: Stir from the bottom of the can to the top before use
• Thinning/Reducing: When spraying, thinning is generally not required, but if needed, 5–10% is normally adequate
• Apply in thin overlapping coats: At least three thin, even coats; multiple thin coats are better than a few thick ones
• Re-coating: Once the previous coat is dry to the touch (2–6 hours), apply additional coats within 8 hours
• Coating over rust: KBS RustSeal can be applied over light surface rust treated with RustBlast if desired
• Cure time: The area can be handled after 1 day, and full cure takes place in 7 days
• Full instructions HERE

Once fully cured, the metal is sealed against rust and ready for the Bed Liner topcoat.

How Do You Apply KBS Bed Liner for Maximum Durability?

Before application of KBS Bed Liner scuff the fully cured KBS RustSeal with 320 grit sandpaper for best adhesion of Bed Liner.

• The surface must be clean, bone dry, non-glossy
• Do not apply when the air temperature and the temperature of the skid plate is below 50°F or above 90°F
• Thinning KBS Bed Liner is not recommended. The addition of thinner can possibly affect the performance characteristics of this coating
• When spraying, use a Shutz style spray gun or HVLP spray gun
• Spray 18-24” away from the surface in long, sweeping motions
• On the first pass apply a thin coat to provide a base for heavier subsequent coats. This improves adhesion so KBS Bed Liner does not run off smooth surfaces or sag on vertical surfaces
• Be sure to vary the spray paths to avoid any “shadowing” patterns from forming
• When rolling, apply using a high-quality solvent resistant textured foam roller
• For maximum durability, apply 2–3 thin coats, avoiding heavy passes
• Recoating can be done once first or consecutive coat is dry-to-touch
• Allow 72 hours for full cure before putting the skid plate into service
• Full instructions HERE

This is your protective armor layer—perfect for off-road skid plate coating and long-term impact resistance.
