Does anyone with a brush guard ever have a need for one? Can’t tell you how many Australian Outback cars that look like they’re outfitted for Crocodile Dundee are lined up at the Piggley Wiggley buying a quart of milk. But to address the question, most car washes in New Jersey have a disclaimer posted outside that they’re not responsible for damage to such add ons. Real off roaders would never be caught dead at a car wash.
