Tell the car wash guy to turn off the overhead brushes. They do it for my wife's escape that has a Thule kayak rack on top.Great review a question for you guys/gals that have your trucks am worried about the antenna mast. Have you been through a car wash? the car washes in my area have a MONSTER brush that cover hood, roof, trunk. I don't mind washing my vehicles weather permitting but when it gets cold I go to the car wash. Do you remove the mast, it comes off right??
