An ignorant newbie here. I removed the padded door panel on the inside of the door to my 84 toyota truck and the plastic (dust sheathing?) was so old I intend to just cut a new one from plastic sheathing I got at home depot. Anyway, what is the glue to use? I noticed the original was held on by a removable tar-like substance. Does it matter? Do I just use any adhesive I have lying around? I assume that the type of plastic used is not too important only that it gets the job done. Thanks!
