All I can really say is Great Lakes Undercoating is simply Amazing! Martin was great to work with, and was willing to discuss and explain everything. I drove over an hour to have my 98 Wrangler done, and to be honest, I'd drive 4 hours more if need be to have the work completed by Martin. Their meticulous attention to detail is unmatched. Thank you Martin, and your whole team, for your wonderful work. You have a lifetime customer in me for sure.

Hi Martin and Crew, I just wanted to take a moment to send a sincere thank you to you, Martin, and your entire team—especially your dad. You guys went all out on my vehicle, showing incredible attention to detail when applying the woolwax. The job was thorough and every bit as professional as I expected it to be based on your reviews. I drove all the way from Evanston, Illinois, even though there is a local provider nearby, because your reputation was just too good to pass up. I am so glad I made the trip and decided to get the additional wheel liners as well; if you're going to treat one area of the car, you might as well treat the whole thing. I will definitely be coming back to have this work done as needed for as long as you and your crew are there. Bravo to all of you on the fantastic work. I’ve attached some photos to show just how great everything looks.

I brought GLU a 2011 Sierra 2500HD. It came from Canada and had very little surface rust. Martin was outstanding and communicated all aspects of the job thoroughly. During the undercarriage wash process he found approx. 30 pounds of sand inside the frame rails and spent extra time time getting it flushed out. If that wasn't impressive enough, his attention to detail is fantastic. Literally no overspray. Under the hood coating (which I didn't expect) was so well done, it looks detailed and better than new. This company knows what their doing. I Highly Recommend Great Lakes Undercoating LLC.

We recently had our Sprinter 3500 Winnebago RV treated at Great Lakes Undercoating and highly recommend Martin for his professional, thorough service. His attention to detail and the comprehensive Woolwax rust-protection coverage gave us real confidence that the underbody and key areas were properly protected. If you’re looking for high-quality undercoating or rust prevention for a van, truck, or RV, Great Lakes Undercoating is an excellent choice.

I brought my new car in to get prepped for winter - these guys were super good. They talked me through the whole process, sent pics of what all they did as they were doing it, and walked me around the car afterwards to show their work. Very thoughtful and thorough. I would recommend them to anyone

Very competitive pricing. Superior customer service. I did the research to find exactly what I wanted in undercarriage protection, just needed the right local provider. These guys were top-notch. Quite satisfied.
