As once told to me by the old Ziebart dealer. Undercoating comes in 3 packages, basic, deluxe, and supreme. For the basic package, he would put your car on the lift and apply the undercoating. For the Deluxe package, he would put your car on the lift and apply the undercoating while smoking a cigarette. For the Supreme package, he put your car on the lift, applied the undercoating, smoked his Marlboro AND inscribed his initials under your car when done.
