At Michalak’s Auto Repair in Souderton, we know that Pennsylvania weather can be tough on vehicles.
From coarse salt and brine on winter roads to year-round moisture, rust is one of the biggest threats to your car or truck’s lifespan.
That’s why we proudly offer NHOU® Oil Undercoating: a proven solution designed to stop corrosion before it starts and protect your investment for years to come.
Why Choose Oil Undercoating?
Traditional rustproofing products tend to harden over time, crack, and allow water and salt to creep in. NHOU®’s oil-based formula is different.
It remains fluid so it can fill the seams, cracks, and hidden metal surfaces where rust usually forms. This self-healing action not only coats, but also displaces moisture and oxygen: two of the main culprits behind corrosion.
The result? A vehicle that stays solid, safe, and looking its best.
NHOU® Product Options and Benefits
NHOU® offers a variety of undercoating products to meet different needs, and at Michalak’s Auto Repair, we can help you select the right one for your vehicle. Some of the options include:
- Traditional NHOU® Oil Undercoating (Clear or Black)
As the foundation of NHOU®’s lineup, this product delivers superior rust protection by creating a penetrating barrier against moisture and road salt. It’s environmentally friendly, non-toxic, and won’t dry out or crack. The black version provides a uniform finish for a clean, factory-new look underneath your car, while the clear option allows you to easily inspect surfaces over time.
- NHOU® Boss Wax
Ideal for heavily rusted vehicles, Boss Wax offers a thicker wax-oil blend that clings to rougher surfaces. It seals out contaminants and extends the life of vehicles already showing signs of corrosion.
- NHOU® Rodent Repellent Undercoating
One of the most innovative solutions available, this formula combines all the rust-fighting benefits of the standard oil undercoating with a natural rodent-repelling additive. Mice and squirrels often chew wiring, insulation, and plastic components, leading to costly repairs. This specialized coating discourages them from nesting in or damaging your vehicle: an invaluable safeguard for anyone who parks outdoors or stores their vehicles in barns or garages.
Ensuring Long-Term Value
NHOU® Oil Undercoating isn’t just about protecting metal—it’s about saving money and avoiding headaches. By preventing rust and corrosion, you extend the life of your vehicle’s frame, brake lines, fuel lines, and other vital components. The long-term benefits? Fewer repairs, greater reliability, and higher resale value.
