If you’ve been driving your Corvette long, chances are you haven’t noticed that the weatherstripping is showing signs of age. It’s probably not an area you commonly check, like oil or paint, and the howl of wind noise has a tendency to creep up on you, instead of suddenly getting really loud.
Not sure if your car is a candidate for fresh ’stripping? Try this simple test: The next time you go for a spin, take a minute to turn down the music, lay off the loud pedal, and listen to the interior noise with the windows up. If you’ve got any kind of mileage or years on your prized possession, you’ll likely notice quite the racket as air rushes past those old, dried-out seals and into the cabin. Was it always that noisy? Doubtful.
For Steve Hardy, that racket was becoming unbearable, but it wasn’t until he noticed water entering the cabin on rainy days that he became suspicious of the weatherstripping in his LS1-powered ’87. And it didn’t take much inspecting to realize that the old stuff was literally falling apart at the seams, showing signs of aging, compression, and flat-out failure in multiple areas.
It was obvious Hardy’s C4 needed a complete weatherstripping overhaul, so he contacted the resto-parts experts at Corvette America and ordered up a full complement of fresh seals. Those, and a day’s worth of work, were all that was needed to return the ’87 to its original moisture-free, (semi-)silent state. Let’s take a closer look at the job.
It’s safe to say that all of the weatherstripping on our test vehicle was shot.
