Yeah, we have one of those here in town. Easiest way to clean the undercarriage gunk. I, too, hate the winter months. I so wish I lived in Florida or South Carolina. Big NO from my wife because all of our family is here.Yours is looking killer all nice and clean and tucked away for the winter months.
I go through the touchless car wash a couple of times during the winter months and it has an option to do the undercarriage, which I always pay extra for.
I hate the winter months. LOL
