It’s never “too late” to have your vehicle protected. Dakota Rustproofing can help stop existing rust on contact.  Save costly repairs on brake lines, rocker panels, springs, and rusting frames with our Woolwax® undercarriage coating.

Not JUST for winter protection!  Salts and fertilizer residue WILL stick in all those hidden areas on your car or truck ALL YEAR LONG.

Summer rains will re-activate those chemicals and really corrode during the summer months.

Get year-round protection from “Those rust stop guys!”.

We just do one thing and we do it extremely well.

The destructive force of corrosion is the single greatest threat to your vehicle. Constant exposure to a wide range of elements such as sun, rain, wind and snow can lead to rapid deterioration of metal, not only resulting in poor appearance and loss of value, but hazardous safety issues as well. Road salt, brine and debris also kick up and cling to vehicle under-bodies, eating away at metal, electrical connections, hydraulic lines and fuel lines!

How does this work ?
Dakota Rustproofing protects all undercarriage metals by creating a non-drying barrier that seals out moisture and air. With the barrier in place, existing rust will be stopped on contact, and new rust and corrosion cannot develop. Our process penetrates to the base metal, remaining active and migrating to inaccessible areas. WOOLWAX® provides long term protection from the corrosive effects of salts, calcium chloride, moisture and fertilizers.

It generally takes about 60-90 minutes per vehicle to treat.  We clean and treat ALL hidden areas, frame, cab corners, rockers, doorskins etc from the INSIDE using wands, sprayers and applicators.  Can be driven immediately and will not drip.  Waiting area is available or drop off and vehicle pickup is available.  We can handle ANY size vehicle in our shop and we can travel for Fleet vehicles if needed. Contact us for more information.  See PRICING for general pricing.  We now have BLACK available along with our powerful clear product.

Dakota Rustproofing uses a clean simple and safe process to provide long term corrosion protection for any vehicle. There have always been two popular methods of vehicle undercoating. Permanent one-time hard shell (rubberized/epoxy), and annual soft coatings such as WOOLWAX®. The downside of the permanent hard undercoatings is that they will chip and become porous, allowing moisture to get trapped between the coating and the undercarriage. Your vehicle will rust away and you wont know it until it’s too late. Our product does not dry, but forms a gel film-like barrier that moisture and oxygen cannot penetrate. Without the moisture and oxygen rust cannot occur.  Our product is self-healing. If it gets scraped or comes into contact with a foreign object, it will simply gel over itself. WOOLWAX® is formulated to be thicker and more resistant to wash-off than any other soft undercoating. A single treatment will generally provide complete protection for 10-12 months. In the enclosed environments (doors, rockers, frame rails, etc.) that are not exposed to the elements, the protection will last indefinitely (years). The exposed areas of the undercarriage may need to be treated annually.

We use an industrial grade lanolin based gel, blended with advanced corrosion inhibitors that prevents corrosion and completely STOPS existing rust.  Will not evaporate, dry, get tacky or gummy.  Anti-corrosive coating, lubricant and penetrant for all metals, automotive paints, plastics and more!  Using high-pressure wands, applicators and brushes we treat all hidden areas of your vehicle. Our automobile rustproofing helps stop and prevent your vehicles from rusting.

  • Non-Toxic, solvent free and safe for all automotive finishes.
  • Helps prevent rust from forming.
  • Helps stop existing rust and corrosion from spreading.
  • Will not trap water underneath it
  • It is not a sprayed in “liner” coating. It WILL NOT scratch off or trap water.

Protect, seal, and rustproof your frame, pinch-seams and wheel-arches with a self-healing powerful rust-inhibitor.  Since 1943! If you’re looking for rustproofing near me, please give us a call.

We also travel for large fleet and AG orders too.
