NHOU St. Croix Valley

I took my F150 to Marc at NHOU St. Croix Valley and now I’m convinced he’s not just a rust prevention expert, he’s the Gandalf of undercarriage wizardry. “You shall not rust” feels very on brand.

I can’t recommend this place enough! The owners/operators are the most friendly people. Very very educated and walk you through the process from start to finish. My truck looks fantastic and I will be back.

Very happy with the product! The owner ( I cannot remember his name) was wonderful to talk with. Very thorough and very, very nice guy! Did not try to upsell. Understood what I was looking to do and absolutely nailed it! Thank you again and would recommend to anyone!

Fantastic place. Great customer service! If you want your cars to survive the brutal pressure of winters and salt, you must check this place out. I wish I knew it a couple of years ago. Both our cars were treated. Will return and highly recommend.
