Are your interior plastics sticky or bleeding color? November 02, 2015, 10:15:12 AM I'm not sure if my issue is unique due to using a harsh chemical to clean, or if these parts are just degrading..The color is rubbing off my door panels/armrests. They're also very sticky. I have a feeling my only recourse is going to be replace the parts.. I'll get a list of the affected parts and come back here to go shopping. :)Anyone else have this issue?

Are your interior plastics sticky or bleeding color? Reply #1 – November 02, 2015, 10:26:50 AM I've had more problems with fading or discoloration than anything else. That's probably just due to time and atmosphere. Whatever you're experiencing is probably normal for ~30-year-old plastics. Also, warmer climates will cause the interior panels to bleed and warp/discolor a lot more. I know you're only ~250 miles away but Cincy is always warmer than Youngstown, and your summers are definitely more intense.The only true way to "fix" the issue is to remove the panel, sand it lightly, use a good wax/grease prep, use an adhesion promotor, and respray the panel with a quality interior lacquer. I have never found any other "magic" fix. Even getting the panels recovered in vinyl has its own issues.The OEM door panels on the '86 are different from each other: one side has held paint flawlessly from day one (1999-sh). The other side has required repainting every 3-4 years no matter what I try. It always stays tacky and rubs off on clothing. This year I did a full strip, heavy sand, and multi coats of adhesion promoter with a lot of drying time in-between. Seems to have done the trick. It's just something in the plastic on the one door panel...the other side is fine. Quote Selected

Are your interior plastics sticky or bleeding color? Reply #3 – November 03, 2015, 10:09:08 AM This prompted some interesting searching. I was blown away to find this particular result/problem/discussion: Ferraris. http://www.ferrari101.com/forum/360-430-sponsored-yellow-compass-group/165540-solution%94-melting-sticky-rubber-plastic-interior-pieces.htmlNow try and stay jealous the next time you see some high roller in a 360 Modena Did you clean anything with harsh chems as you hinted at? I'm not a chemist but you might have jump-started a decomposition of the material. That's most likely what you are seeing. My guess is oxidation, really shouldn't be likely to react with nitrogen or argon or other trace elements in the air. Sun exposure also doesn't help. But the plastic compound is decomposing in some way.Eric's method will passivate the surface, like rust if you successfully seal it in, it cannot continue. Or you could cut down the material and expose "fresh" stuff and you may or may not need to seal in THAT too. I wonder if there is some outer layer that does just this when it's initially manufactured. The guy whose job I now have because he quit, has his M.S. in Chem Engineering, and is a big motorhead as well. He insists that dashboards splitting and cracking on older vehicles throughout the 70's and 80's was due to poor plasticizers. Those are apparently additives that help make the dashtops ductile and flexible. I'll have to ask him about this. If nothing else he'll ramble on for an hour and I'll be stuck there but I'll come away with some random trivia LOL Quote Selected
Are your interior plastics sticky or bleeding color? Reply #4 – November 03, 2015, 10:29:48 AM It's tough to cut down the surface and expose new molded color because of the graining on the outer surface. Otherwise sanding would be a great solution, at least for a few times.The interior on my '84 rarely sees daylight. That car has always been garaged since new (old people owned, then on to me). And yet the kick panels have yellowed. So it's not me, it's not my environment...has to be something with the plastics... Quote Selected
Are your interior plastics sticky or bleeding color? Reply #5 – November 03, 2015, 11:49:00 AM My Thunderbird spent the first 14 years of it's existence in So Cal and the next 13 here in Chicago. I don't have an issue with the plastics getting sticky or deforming. It's been garaged all the time which may help. I'm betting it has more to do with sun exposure or the chemicals used to clean the plastic than anything else. Quote Selected
Are your interior plastics sticky or bleeding color? Reply #6 – November 03, 2015, 08:24:13 PM my 87 has been in a garage all its life, the interior is like new although the bottom part of my armrests have unglued from the metal frame and is pulling away a bit. still not complaining though... I'm putting my money on sun, or heat damage is what most people have.. I have never used anything other then windex to clean all my interior plastic, and vinyl... last year I gooped the dash with petroleum jelly... been softer and more pliable ever since Quote Selected

Are your interior plastics sticky or bleeding color? Reply #10 – February 20, 2016, 07:31:34 PM The arm rests on both side doors of my 84 TBird are both sticky and look like someone sprayed glue on them. My car has been in extreme hot temps for most of its life... I guess it's a chemical reaction from the heat... I'm trying to find some type of cleaner that will get rid of this mess... Quote Selected
Are your interior plastics sticky or bleeding color? Reply #11 – February 20, 2016, 07:47:39 PM Steve, Welcome to the forum. Search Meguiars products. They may have something and are at most auto parts stores. I have used something called "TUFF-STUFF" for years. It is sold at auto parts stores and even Wal-Mart. Spray on and let it soak, scrub with a brush works pretty well. I detailed cars for extra money when I was younger and got great results with it. Good luck and post some pics of your Bird when you can. , Ray. Quote Selected

Sometimes when I'm stuck in traffic or waiting in the car I pull the key out and se the edges of the steering wheel. Goopy booger looking peices rub off. Quote Selected

Are your interior plastics sticky or bleeding color? Reply #14 – February 29, 2016, 02:48:03 AM I just bought a 87 turbo coupe the part under the armrest on the door panels were sticky. I though maybe someone tried to clean them with something or spilled something on them, but then the interior is in mint condition. Mine are red. I also posted in the parts forum, because I'm looking for some driver side door panel parts someone must have tried to take them off and broke a bunch of the plastic parts on the door panel.
