Many drivers picture rustproofing as a quick spray under the car, but at Paint Bull Express, the process is much more detailed. A professional application is what separates real protection from the cheap jobs that leave gaps and weak spots. Here’s how we do it.
Step 1: Free consultation
We start by talking with you about your vehicle, its age, and how you use it. A daily driver in Michigan winters needs a different plan than a weekend cruiser.
Step 2: Inspection
Our technicians check for any signs of existing rust, paying close attention to seams, brake lines, and suspension components. If corrosion has started, we can recommend NHOU Rustoration to stop it from spreading.
Step 3: Surface preparation
The undercarriage is cleaned and prepped. This step is critical because dirt and grime can prevent coatings from bonding properly.
Step 4: Application
Using specialized tools and cavity wands, our team sprays NHOU into every seam, weld, and panel cavity. Oil-based products creep into tight spaces, while BossWax provides a thick, waxy shell for new vehicles.
Step 5: Quality check
Every vehicle is reinspected to make sure coverage is complete. Missed spots are touched up immediately.
Step 6: Final wash
Your car leaves looking clean, with the undercarriage fully protected.
This careful process is why Paint Bull Express stands out. Rustproofing isn’t just about the product — it’s about how it’s applied. Our technicians are trained to cover areas that factory sprays and DIY kits often miss.
The best part? With an annual inspection and refresh for just $40 (including a free car wash), you can keep your protection strong for years. Compared to thousands in repair costs, professional rustproofing is one of the smartest investments you can make for your vehicle.
Don’t settle for shortcuts. Get rustproofing done the right way.
