Regular inspections are your first line of defense against wind leaks. These checks allow you to catch potential problems early, before they escalate into significant issues.

Frequency: Aim for a thorough inspection at least twice a year, ideally coinciding with seasonal changes. Spring and fall are excellent times, as you’ll likely encounter fluctuating temperatures and increased exposure to the elements.
What to look for: Carefully examine all door seals, window seals, and weather stripping around the trunk and sunroof (if applicable). Look for any signs of cracking, tearing, compression, or displacement. Also, check for any areas where the seal is no longer making firm contact with the body of the car.
Tools: A flashlight is your best friend during these inspections. It helps illuminate hard-to-reach areas and highlights any imperfections in the seals. You might also want a small, blunt tool (like a plastic trim removal tool) to gently pry back seals for closer inspection.

Methods for Cleaning and Protecting Weather Stripping

Weather stripping, like any part of your car, requires proper care to maintain its effectiveness and longevity. Regular cleaning and protection are key.

Cleaning: Start by cleaning the weather stripping with a mild soap and water solution. Avoid harsh chemicals, as they can damage the rubber. Use a soft cloth or sponge to gently wipe away dirt, grime, and debris. Rinse thoroughly with clean water and allow the weather stripping to dry completely.
Protection: Once clean and dry, apply a weather stripping protectant. These products typically contain silicone or other lubricants that help to prevent the rubber from drying out, cracking, and sticking to the car’s body. Apply the protectant according to the manufacturer’s instructions, and wipe away any excess.
Examples of Protectants: Silicone sprays, rubber protectant conditioners, and dedicated weather stripping treatments are readily available at auto parts stores. Choose a product that is specifically designed for automotive weather stripping.

Signs Indicating That the Windproofing Measures Need to Be Re-Evaluated

Be vigilant for warning signs that indicate your windproofing efforts are beginning to fail. Early detection allows you to address the issues before they become major headaches.

Increased Wind Noise: A sudden increase in wind noise, especially at higher speeds, is a primary indicator of a problem. If you notice a whistling, roaring, or hissing sound that wasn’t there before, it’s time to investigate.
Water Leaks: Water leaking into the car after rain or car washes is a clear sign that the seals are compromised. This could be due to cracks, tears, or compression of the weather stripping.
Drafts: Feeling a draft around the doors or windows, even when they are closed, is a telltale sign of wind leakage. This often occurs in the form of cold air entering during the winter or warm air during the summer.
Visible Damage: Any visible damage to the weather stripping, such as cracks, tears, or compression, is a clear indication that it needs attention. These issues will compromise the seal’s effectiveness.
Difficulty Closing Doors or Windows: If you notice that your doors or windows are becoming more difficult to close or seal properly, this could be due to worn or damaged weather stripping.
Musty Odors: The presence of musty odors inside the car can indicate moisture buildup, which may be caused by water leaks resulting from failing windproofing measures.
