Inside door panel plastic replacement?

[ShadowKlown]

I searched, I may have missed it, I apologize if so.

I'm also not sure if this question belongs here or the other beginner thread.

I'm stripping down the carpet panel sections on the doors to redo them with the vinyl diy on here, and also have to fix the driver window track on the driver door and replace the motor in the back rear door.

Long story short, I have to take off that crappy 23 y/o plastic lining inside the doors. Should I replace it? Do I have to? With what? My neighbor suggested the black anti-weed plastic(cuz it's pretty thick he said) that they sell at like lowe's, thoughts?

Thanks in advance.

if you don't tear it, i see no point in replacing it, but if you do, that weed stuff sounds ideal. later.

I recently had to take that plastic off of my drivers side door. I took it off in a way where I could make a good template from it which I don't think is completely necessary but it helped me cut the new one. I took the time and pealed as much of the old adhesive off as I could before applying new plastic.

I used clear construction film from Lowes. This stuff. http://www.lowes.com/pd_16955-18632-...oll&facetInfo=

And Loctite construction adheisive. http://www.lowes.com/pd_100575-69-17...ive&facetInfo=

Thanks for the info, will have to swing over n see which route is the most cost effective since I seem to always be broke

There are other materials that can be used. These were easy to find and relatively cheap. And I chose materials that I though would be available in the future. In other words Lowes had a lot of both of these products on hand.

As Type G stated, if you don't destroy or stretch the plastic that it already has, the adhesive is still tacky and will stick back in place. I however did not do that out of ignorance of that fact.

that plastic is mostly for wind noise then anything else (unlike some other models where it is mandatory to keep the water from leaking inside the car...like most new bmw models for exemple)

meaning u dont HAVE to reinstall it, if you rip it and dont want to take time to buy/fabricate a new one with other plastic from hardware stores, you could always use duct tape to fix the parts u ripped off...

but while your in there it could also be a good time to upgrade for something better like dynamat http://http://www.b-quiet.com/dynamat.html

whenever i remove those plastics from any cars (being a body man i do that often) i use a blade or a metal bondo spatula that i sharpened for that purpose to avoid ripping it

you can use ''dumdum'' (butyl strings) to stick them back on.

I honestly don't know what its for other than to keep rain or water from possibly getting to the electrical components on the back side of the door panel. That and maybe a dust/dirt barrier and partly for sound dampening. I can't remember if my S14 has it or not.

I got fed up with mine and ripped it out completely years ago. I've never noticed any negative effects of doing so. The car is parked outside, and has been through all sorts of weather. Never any leaks. The exhaust is loud, so it's pretty tough to tell if the noise increased as a result of removing it... so it might make a difference if your car is stock.

The main reason for it is to prevent dust from gravel roads getting inside the cabin.
