The Importance of Protecting Your Vehicle’s Weather Stripping

Car door frozen shut by winter ice. Ice can cause damage to your weather stripping. The rubber weather stripping on vehicles does several important jobs in order to keep a vehicle safe and secure. Protecting this rubber weather stripping is important to ensure a longer use without the expense and bother of replacing it. Taking care of this weatherstripping properly will pay for itself in the long run.

What Is Weather Stripping?

Weather stripping on vehicles is made of rubber and lines the doors and windows. It ensures the doors seal properly when closed. This seal will fend off the elements, and prevent water from leaking inside the vehicle. It is further used on windows to seal and protect the windows. Because it is on the outside of the vehicle it is subject to the harsh weather conditions such as rain, snow, ice, UV rays and dirt which damage the rubber. All of these can wear down the weather stripping over time.

So what happens when weatherstripping gets worn down?

Vehicle Doors

When the weather stripping fails on any part of a vehicle it creates problems. Doors with failed weather stripping are not tight when closed. When this happens, water may seep in and create problems such as mold and rust. In the winter these doors may not open properly because the metal door will stick to the metal door frame if the weather stripping is gone.

Vehicle Windows

Windows need weather stripping even more than doors. The windshield goes through all types of weather and failing to weather strip a windshield and other car windows will allow rain as well as noise and dirt to enter the vehicle. While noise can be both annoying and distracting, letting water into the vehicle can cause even more problems down the road. Dirt buildup inside a car can shorten the life of the upholstery and carpets.

What can you do to keep your weather stripping like new?
