Shout out to Nick Sjaarda for bringing his 2009 GMC Sierra 2500HD to get a full "Box Off" rustproofing and undercoating using only the best, Woolwax Automotive Undercoating. We took the time to remove all flaky rust from the frame and underbody before cleaning out all debris from inside frame rails and cross members. Followed by checking and opening all drain-ports in rockers and doors. Once it looks the way we want our own vehicle to look, we meticulously cover all ferrous and non-ferrous metals, inside and out with the hands down best soft undercoating product on the market. We have been proudly using and promoting all Woolwax products both personally and professionally for nearly 10 years. Nick was quite pleased with the amount of detailed work we did, and we are looking forward to seeing him next year for his half-price annual retreatment and inspection. We are proud to be your one stop shop for all automotive corrosion related issues. Check out our website at www.midwest-rust.com for scheduling or give us a call at 605-418-8355. Book today for a rust-free tomorrow!
Open 7 days a week. 9am-7pm. By appointment only, please.

Please don't be this person. A sad fact that everyone should realize is that Vehicles begin to rust and corrode while they're still on the factory floor. If I tried to recall every vehicle that I have undercoated and rustproofed that had less than 200 miles on the odometer and had surface rust already formed on the driveshafts, power steering pumps(especially), and other components, I'd be doing it all day long. Corrosion tens to hide out of sight and out of mind until start to see the bubbling, which is a clear indicator of a much larger, hidden corrosion issue. We live in the Rust Belt folks, getting your vehicle treated for corrosion is a no-brainer that ought to come as second nature to car buyers living here. Check us out on Google, Facebook, and always at www.midwest-rust.com.
I AM FUMING. I took my car in for a simple oil change yesterday at the dealership and I get it back looking like this! The stupid mechanic tried to tell me it is long term rust from road salt and that the metal is rotting away. Rotting?! My car was perfectly fine when I dropped it off! They clearly spilled some kind of crazy acid chemical on it and are trying to cover up their gross incompetence. I am calling my lawyer and suing them for property damage because I know for a fact this happened in their garage while they had it. Am I overreacting for demanding they buy me a brand new vehicle to replace this ruined one??

Shout out to Joshua Nelson for bringing in his 2026 Toyota Tacoma all the way down from Fargo, ND to get rustproofed and undercoated with Woolwax Automotive Undercoating. Immediately after purchasing this truck, Josh scheduled an appointment on our website, wanting to get his investment protected ASAP from corrosion caused by our rough winters and accelerated by the salt and brine that all our states dump across the roadways. We made sure to generously treat inside of every cavity and nook including the rockers, frame rails, cross members, doors, hood, tailgate, fender wells, and much more. We also make sure to treat all lock assemblies and hinge points since Woolwax is also an amazing penetrant and lubricant, keeping frozen latches and squeaks to a minimum. Our entire process took only a few hours to complete, but now Josh can drive back home to the foot or two of accumulated snow waiting for him without any worry. If you or someone you know is interested in keeping rust from destroying your investments, then check out our website at www.midwest-rust.com for scheduling and more information. We are open 7 days a week, by appointment only, and can be easily reached at 605-418-8355. Book today for a rust-free tomorrow!

Shout out to Steve Clark for bringing in his wife's 2013 Ram 1500 Bighorn to get rustproofed and undercoated with Woolwax Automotive Undercoating. Since there was a large tear in the corner of the tonneau cover, Steve asked if we could replace it with a brand-new one he had previously purchased but hadn't found the free time to do himself, which of course we agreed. At Midwest Rust Prevention we not only excel at erasing corrosion, we also take time to accommodate customer requests to the very best of our abilities. After we cleaned out the frame rails, doors, rockers, and cross-members of loose debris and dirt, we made sure to needle-scale away all areas where rust had been getting thick and worrisome. Once removed, we apply generous amounts of rust-killing/inhibiting products before finally treating the entire underbody and inside all plugged compartments with Original Woolwax. Interested in protecting your investment from the destruction caused by salt and brine this winter? Then give us a call at 605-418-8355 or easily schedule your appointment online, anytime at www.midwest-rust.com today! Open 7 days-a-week, 9am-7pm. Book today for a rust-free tomorrow!!

Shout out to Heather Rios for making it in during a wicked snowstorm to get her 2023 Ford Mustang rustproofed and undercoated with Woolwax Auto Undercoating. We were able to take our time with this beast since Heather had to get home ASAP and the roads proved too hazardous to attempt in a rear-wheeled vehicle. We gave her a ride home with the assurance that her Mustang was completely safe and secure overnight and would receive the best care. After we treated the underbody and rustproofed all the nooks n' crannies, we made a few minor repairs on pre-existing issues and replaced a few missing body plugs. When the roads were finally safe to drive on the next morning , Heather had her rumbling rod delivered to her home free of charge. I thank you again for you're patience and flexibility under the circumstances. If you are interested in quality rustproofing, no matter the weather, then book your appointment at www.midwest-rust.com or give us a call at 605-418-8355. Open 7-days a week, 9am-7pm. Book today for a rust-free tomorrow!! (*All vehicles are pre-treated with a powerful road salt neutralizer prior to any work perfomed.)
