Does anyone have experience with lining the inside of vehicle (floor only basically) with some sort of waterproof protective coating? I have no carpet in the rear, and the carpet in the front smells like mildew (broken door seal used to leak) so I would like to rip it all out and coat the floor with something durable/waterproof. any suggestions tips? i.e. what to do about the wires running along the floor or areas to be aware of. thanks much
