Protection for Midwest Roads
Outlast Salt, Slush, and Rust With Our Rugged Vehicle Undercoatings
Vehicle Undercoatings Provide Protection that Goes the Extra Mile
Protect your vehicle from Rochester’s harsh winters and salty roads with professional undercoating from Five Star Auto Detailing. We use WoolWax, a lanolin-based formula designed to penetrate deep into frame rails, seams, and hidden cavities. Unlike traditional undercoatings that just sit on the surface, WoolWax creeps into tight spaces and stays flexible over time, providing long-lasting protection against moisture and corrosion. Whether you're driving through slush, salt, or spring rains, our thorough prep process and premium product ensure your undercarriage stays strong and rust-free for years to come.

Why Get an Undercoating in Rochester, MN?
Rochester winters are no joke, and neither is the damage road salt and slush can do to your vehicle. Here are the top 3 reasons local drivers trust Five Star Automotive Detailing for professional undercoating.
Midwest Roads Mean Serious Rust Risk
Rochester’s long winters and salt-covered roads accelerate rust like few other places. Our WoolWax undercoatings form a durable, salt-resistant barrier that protects your vehicle’s most vulnerable areas from corrosion season after season
Professional Prep for Long-Term Protection
We don’t cut corners. Your undercarriage gets a full salt-neutralizing wash, underbody plugs are removed for internal treatment, and minor rust is needle-scaled when needed. The result is a cleaner, more effective undercoating that lasts.
Keep It Covered, Year After Year
Rust doesn’t take a break, and your vehicle’s protection shouldn’t either. We recommend quick touch-ups every 1-3 years, depending on how and where you drive, to keep your undercoating performing its best.
Undercoating FAQ for Rochester, MN Drivers
Got a question? We’re here to help.
Why is undercoating especially important in Rochester, MN?
Rochester sees plenty of snow, slush, and salted roads—exactly the kind of conditions that accelerate rust and corrosion. An undercoating acts as a barrier between your vehicle’s undercarriage and all that moisture and salt, helping prevent long-term damage. It's not just helpful here. It’s essential.
What kind of undercoating do you use?
We use WoolWax Creep N Crawl, a high-performance, semi-solid undercoating and cavity wax. Unlike old-school tar-based products, WoolWax doesn’t crack or dry out. Instead, it creeps into seams, frame rails, and tight spots to provide long-lasting protection even through Rochester’s harsh winters.
How long does the undercoating last?
A single application of our WoolWax undercoating typically protects your vehicle for 5+ years. That said, we recommend touch-ups every 1-3 years, depending on how often you drive, where you park, and what kind of road conditions your vehicle faces. Touch-ups start at just $150 and keep your protection going strong.
Do you prep the vehicle before applying undercoating?
Absolutely. We thoroughly wash and flush out the undercarriage with a salt-neutralizer, remove underbody plugs to treat inside structural components, and even needle-scale light surface rust when needed. This attention to detail ensures the product adheres properly and delivers long-term results.
Will undercoating affect how my vehicle looks or drives?
Not at all. Undercoating is applied to the underside of your vehicle and won’t change its appearance. What it will do is make your car or truck quieter on the road by dampening road noise, and more importantly, it’ll help preserve the integrity of your frame and components underneath.

What to Expect During Your Appointment
We treat every vehicle like it’s our own. When you bring your car, truck, or SUV in for an undercoating, here’s what the process looks like.
Step 1: Salt-Neutralizing Wash
We start by flushing out the undercarriage to remove road grime, salt, and buildup that could interfere with the coating.
Step 2: Full Prep Work
Our team removes underbody plugs and inspects structural components. If there’s any light rust, we’ll perform needle-scaling to clean it up before applying the product.
Step 3: Application of WoolWax
We apply our premium undercoating and cavity wax with precision using 360° misting wands and 90° tips to reach tight, hidden spaces like frame rails, rockers, and inner panels.
Step 4: Dry Time and Final Check
We allow the product to cure and inspect for full, even coverage. Most appointments are done within a day, and you’ll be back on the road with protection that lasts for years.
