How to Protect Car Weatherstripping From its 2 Big Enemies: Heat & Frost Damage

Be honest with yourself, unless you actively have an issue with your car’s weatherstripping, you don’t think about it at all. It’s easy to forget about until it tears and water starts coming in, which can cause mold and electrical issues!

Weather stripping is expensive to replace and it is difficult to find a roll that matches exactly what your car needs, to maintaining the original weatherstripping will be the most cost-effective method in the long run, plus it helps keep a better seal and keeps it from sticking when things get hot and humid or water tries to freeze your door shut. Plus, getting in and out of a compact car may cause you to rub up on weather strip, so normal wear and tear could cause damage to exposed weather seals, regardless of temperature.

Potential Weatherstrip Damage From Cold & Ice

A door gets frozen shut when water gets into the weatherstripping and freezes, sticking to the texture of the foam. This grease stick fills those pores and also repels water, so the door is less likely to stick if water freezes on the weatherstripping, and less ice will form on it anyway. Water will bead and roll off of this seal protectant, making it helpful when snow and ice melts, too!

Trying to open a frozen shut door may tear weatherstrip material with just one pull, so if you live where this is an issue, this stick is vital! Make sure to coat all of the weatherstrip on both the car and door sides, so nothing sticks! One spot sticking can cause a door to peel off that missed spot, and that will eventually work its way further along.

Potential Weatherstrip Damage From Summer Heat

In southern regions where heat is a bigger issue, the wax will be what sticks to the metal/paint instead of the foam, so this will prevent ripping of the weather seal in the heat, too. The foam can become stronger on the outside than the inside, so when a tear starts, it can get big!

Heat is rough on anything soft, so protecting it keeps you from having to replace it or deal with it being too soft and/or sticky. Heat also melts wax pretty easily, so in extreme environments, you may need to apply this stick more often.

Closing Thoughts

Hopefully this saves you a load of hassle in the long run! Weatherstrip is much easier to deal with before damage is done, so preventative maintenance is the best way to reduce headaches and it will save you money, too. Don’t forget locations like under the hood, your trunk or rear hatch, some sunroofs, and other sealed off sections.
