side note, i noticed your in Vegas. When you apply that matting, make sure your not in direct sunlight, as it will soften the adhesive significantly. Heat is often used to apply rubber mat, but sitting in direct sunlight in Vegas would probably be a little warmer then intended. you will also want to make sure that you roll it into the metal with a hard wooden roller to ensure bonding to the metal. (be careful not to deform the outer sheet metal of the door) you should clean the metal where you want to apply mat with alcohol, do not use brake clean, it will take paint off, the alcohol will as well but to much less of a degree. These steps are recommended everywhere, but in really hot climates they are required or it will not stick well long term. also, do NOT cover wire harnesses with the rubber mat, if you ever need to service one of them, your life, or the mechanics life will be hell, and either way you are going to pay for it. if harnesses are rattling use the foam and put it under the harness, and another piece on the opposite side to sandwich the harness between the foam.
