The L300 WT Van is a product of advanced research and development. It uses state-of-the-art polyurethane adhesive sealants instead of the old rivets. This bonding process has been tested to be stronger than ordinary rivets. Riveted van bodies develop leaks due to metal fatigue which induce loosening. In support of Filipino entrepreneurship, the rear body is made by Metro Truck Builders under the engineering and quality supervision of Mitsubishi Motors Philippines.
