I did a search and cannot find the answer to my question. I am going to apply Dynamat (or equivalent) to the interior of my '52. Going to apply to roof, firewall, under seat, back wall of cab. My question is the floor. I am concerned that if I apply the Dynamat on the floor where to I stop so the Dynamat will not be visable after installing the rubber floor mat and trim. Or, do most simply not apply to the floor at all. I will be undercoating the floor with 3M body Shutz...will that be sufficient?
