What does everyone do for the undercarriage since I won't be taking this through a brushed car wash. How do you get the undercarriage clean, in Michigan we just have a shitload of salt and with my white truck I could get away with once a month running it through a carwash, not this one.......

Brushless car wash. Get the most basic wash that includes undercarriage. In order to compensated for no brushes those type of washes use incredibly strong solvents to strip the dirt from the car. Over time they will strip any protective coatings you use too.
