This weekend I replaced the weather-shield vinyl sheeting in both doors on my '91 Integra. In the process, I discovered that the correct adhesive is "butyl tape", sold by any auto glass place. buys you a 15ft roll, which it appears would do all four doors of a 4-door car. This stuff is sticky and gummy, and remains that way practically forever. Despite its name, "butyl tape" is actually round in cross-section. The stuff I found was 3/8" in diameter. I stretched it to about 3/16-1/4" while installing. I used an old credit card to scrape off the old adhesive, some of which was quite hard after 15 years, and used Sure-Solv auto body cleaning solvent to remove the excess that could not be scraped off. Once you get it all off, you discover that there is a purpose-made channel pressed into the door frame that serves as a receiving location for the bead of butyl. The vinyl itself I replaced with polyethylene vapor barrier normally used for houses. I temporarily taped an oversized piece over top of the existing vinyl, then sketched the pattern on the poly with a marker, attempting to compensate for the shrinkage the vinyl had undergone over the years. A utility knife was then used to cut out the sketched pattern. The above info posted in case anyone Googles for it at some point in the future. An aside: Also noticed that two of the door-glass anti-rattle clips had fallen off the top of the doors. Both had fallen off previously, been put back, but had fallen off again. I just left them off for good. Replacing them means removing the door glass, which I did not feel like doing.
