3M Paint Defender is a liquid auto bra designed for temporary applications. Paint Defender is a spray on urethane designed to protect painted surfaces from damage (rocks, bugs, scratches, etc.).

Uses include transport of new / low mileage vehicles on highways, ‘track days’ for performance / sports cars, or occasional off road excursions. The product is relatively inexpensive and should last up to a year. When needed, Paint Defender should peel off cleanly.
