2020 BMW M340i Sedan The client can drive his car without worrying about rock or bug damage. The ultra-transparent PPF invisibly keeps this paint looking fresh. 3M Crystalline was the tint of choice for this gorgeous BMW. PPF was applied to the door edges and handle pockets. Our technicians tested the audio signal to verify its usability. The front of the BMW was protected with the 3M film. The factory storage pocket was modified to provide cooling access for the ARC Audio amplifier. Our additions kept the interior of this new BMW looking stock. The new BMW’s allow us to use an amplifier after the factory amplifier.
