Sealing doors to keep out dust in the summer and keep the heat in , in winter. I just used 3/8" foam 1" wide with glue on one side and added black silicone adhesive sealant for extra security. I put one strip on the front door pillar of each door and one on each rear door pillar. The front seal gets compressed just a little when door is closed . The rear of the door just clears the seal when closed and leaves 1/16" gap instead of a 3/8" to 1/2" gap, greatly reducing the air flow in and out of the cab.
