Why It Matters

Rust Is Relentless

In South Jersey, your frame fights a four-front war. Once rust takes hold, it doesn't stop. Annual undercoating keeps moisture out and steel intact for the long haul.

Road Salt

NJ winters dump tons of salt on roads, eating into bare metal in a single season.

Coastal Air

Shore-town humidity and salt-laden air accelerate corrosion year-round.

Moisture & Brine

Pre-treatment brine clings to your undercarriage long after the snow melts.

Factory Coating Fails

OEM coatings thin out and chip, leaving frames and seams exposed.

Long-Term Frame Health

A rusted frame totals a perfectly good truck. Protection pays for itself.

Left underneath my truck spotless! Not only is it a mobile service, but the pricing is even better, and the work is even better!! Super easy to schedule and communicate with Clear Guard. I wasn't able to be home for the appointment but he made the communication process better than ever. The work left me in absolute awe — I didn't even believe it was the same truck. If you're looking to get your underframe done, look no where else than Clear Guard! I recommend 20/10 times!

Great service. I've had fluid film sprayed on before but I had to take my vehicle to the place. Alex comes to your house. He is extremely nice and knowledgeable. He even removed whatever rust he could find before spraying on the fluid film. Last place just sprayed on the fluid film — never removed the rust. Great service. Will recommend to everyone!

Very knowledgeable, helpful, and friendly. Expressed to me that my frame condition didn't warrant rust remediation and because of that he took off an additional amount from the agreed price. 10/10 stand up guy. Will be a returning customer.

Great experience overall! Efficient, communicative, and the final results look great. Highly recommend everyone to get this done as the rust only gets worse!
