Car door frame The black plastic on the car door frame is called the door sealing strip. Here is some extended information: 1. Door sealing strip (auto-door-rubber-seal-strip): Mainly used for fixing the door, as well as dustproof and sealing purposes. 2. Features: Primarily composed of ethylene propylene diene monomer (EPDM) rubber foam and dense composite material, which has good elasticity, compression deformation resistance, aging resistance, ozone resistance, chemical resistance, and a wide operating temperature range (-40°C to +120°C). It contains unique metal clamps and tongue-shaped buckles, making it sturdy, durable, and easy to install. 3. Applications: Mainly used on car door frames, side windows, front and rear windshields, engine hoods, and trunk lids, serving functions such as waterproofing, dustproofing, sound insulation, temperature insulation, shock absorption, and decoration.

That thing, I often fiddle with car doors when I'm into car modifications. The black sticker is actually called door edge guard or anti-collision strip. Its purpose is to stick a layer along the door edge to prevent paint scratches when opening and closing the door. I remember the materials are mostly PVC or rubber, cheap and durable, but they tend to fade after a few months, so you need to regularly check if they're still firmly attached. If the sticker loosens or gets damaged and isn't replaced promptly, the door frame can rust after too much rain, and repairs can be costly. When DIYing a new sticker, first clean the door frame thoroughly, dry it, and then slowly align and press it flat—otherwise, too many bubbles will make it look ugly. During regular car washes, be careful not to use hard brushes; a soft cloth will do. Though small, this protective film can save a lot of maintenance hassle and even comes in colors to match the car body, adding a personal touch.

My decade-old car has those black stickers on the door frames, called door edge guards, mainly for scratch protection and paint preservation. The car came with them when new. If accidentally torn, exposed metal can rust quickly, so replacements are needed fast. I tried cheap PVC ones before, but they cracked within months; switching to rubber material proved much more durable, resisting sun and wind without deforming. During car washes, a simple water rinse cleans them, but gently to avoid scratches. These guards not only prevent scrapes but also reduce door-closing noise – highly practical. I’d advise new owners to maintain them regularly, ensuring they’re firmly attached without negligence.

I just learned to drive last year and was curious about the black sticker on the side of the door. A friend told me it's a door edge guard, which protects the door frame from scratches. It's mostly made of plastic, and when applied, it can cushion impacts and reduce damage. Daily maintenance is simple—just rinse it with water during car washes to extend its lifespan. If the sticker falls off, repair it promptly to prevent the door frame from rusting.
