Road Condition Durability Testing
Third Party Testing of the Unconstrained Design
To prove the durability of the unconstrained design, 3M sent two trailers to the
Bosch Automotive Proving Grounds in South Bend, Indiana. The side panels on
one test trailer were attached with 3M

Result: After a simulated 100,000 miles of different road conditions
non-constrained panel construction held tight preventing leaks, absorbing
vibration, and reducing noise. 33% of the mechanical fasteners were
loose at 36,000 miles.
