  • S14 Door Cards / door panels

    Most folks with S14's know that the molded plastic door panels tend to crack with age. Good used examples go for $300-400 for a pair on Fleabay. I got lucky recently and picked up a pair in decent shape from a local junkyard for a good price. Looking on the back of the panels, it lists the material as PPX.

    I looked it up and found several descriptions;

    Here it's described as an alloy of polyphenylene and polypropylene, going by the name of Noryl.

    My 2006 Dodge Dakota has white plastic molded backings for the door cards and I've had to patch the arm rest on that one as well.

    Has anyone tried using bracing, foam, or fiberglass resin to reinforce or repair the panels? The pair I have look good for now, but suspect they'll crack shortly without some form or reinforcement or treatment.

    don't lean on them in corners and don't kick the door open, and you won't have much of a problem cracking the panels.

          I've repaired them using 3M plastic epoxy. It's tedious but as strong as the original material so far. (This is assuming you have cracks, or chunks that have fallen out and can be fit back into the panel.) Missing chunks I'd assume you could use lexan or some other plastic cut to shape to patch the backside of the panel.
