Rust Prevention

Protecting your car or truck from the elements is important for ensuring its longevity. Automotive Protection Services provides the highest quality service on the market for the prevention of corrosion or rust. We exclusively use Noxudol products imported from Sweden and we back our services with a 10 year written warranty to ensure your peace of mind. Our process has been developed over decades and continuously refined as vehicle manufacturers adopt new manufacturing techniques and methods.  One thing has remained a constant throughout the years - metal, when exposed to air and moisture, will oxidize, the salt will accelerate that process and without proper care and attention, all vehicles will corrode given time.

Reach out to our automotive protection shop for more information about all of our rust prevention services and vehicle protection services.


The very first step of any proper undercoating job is to clean the underside of your vehicle.  We use high-pressure power washers, with long wands and angled tips, to reach under your car or truck and remove all of the road grime, salt, mud, and sand. Then we put your vehicle on our four-post drive-on lift. Once in the air, we shine our bright lights underneath and look inside all of the crevices to ensure that we have cleaned out all of the contaminants. Only then do we apply our undercoating.


Rust proofing involves applying cavity wax inside the upper sheet metal of your vehicle. Once applied, it seals out air and moisture which contributes to the formation of rust. We apply our cavity wax on the doors, rocker panels, tailgates, trunk lids, and inside the hood.

Our cavity wax is an impressive product that, along with regular maintenance, will ensure a rust-free body for your vehicle for up to 10 years.

Rust Eliminator

Rust eliminator is a tannic, acid-based product that can restore a rusty metal to a stable compound. We recommend the use of rust eliminator in conjunction with the physical removal of rust scale on a vehicle that is experiencing rust in order to arrest its progress. Once rust eliminator is applied, the chemicals are active and take time to cure (typically 8-12 hours). Once the rust eliminator has fully cured, the metal is ready to be undercoated—leaving it protected against further corrosion.

Contact us to make sure rust doesn’t get a foothold on your vehicle’s body. Our rust protection is available for car owners located throughout the mid-Atlantic region.

Schedule Service

The very first thing that we're going to do is clean the whole underside of your vehicle - remove all the road grime, road salt, mud, grease - anything that contributes to corrosion. Then we'll put the vehicle on our four post drive on lift, put it up in the air and dry the underside of the vehicle with our high-pressure air system. Then we'll apply a thick coating of our abrasion-resistant undercoating to the underside of the vehicle, the floor pans, frame rails, rocker panels - everything on the underside of your vehicle that doesn't move or get hot (like your exhaust system, drive train or shocks).
For a new vehicle - we recommend leaving it with us overnight to allow adequate time for the undercoating to thoroughly cure. For vehicles that require rust remediation work - the process can take a couple of days. (Please call or email).

2 -  How do you apply the undercoating?
- The very first thing that we do whenever we apply undercoating is clean the whole underside of the vehicle - we remove all dirt, mud, salt, chemicals, grease, everything that contributes to corrosion. Then we put the car up in the air using our four-post drive on lift. Once in the air, we dry the underside of the vehicle using our high-pressure air system. Then we remove the spare tire (if it's located under the vehicle). Then we mask off the parts of the vehicle that we're not spraying (exhaust system, drive shaft, shocks). Then we spray the whole vehicle with a thick coating of undercoating - frame rails, floor pans, rocker panels, wheel wells, etc. Then we set it aside and allow the chemical to properly cure.

3 - I've heard undercoating can cause rust - is that true?
