The CLEANEST C3 Corvette Wiper Bay

This video is the Ultimate Guide to C3 Corvette Wiper Cowl restoration, with an in-depth look at everything you need to know about the wiper cowl on your C3 Corvette.

Back in the 1970s and into the early 1980s, Chevrolet chose to ignore the looks of the windshield wiper bay, which is the first thing people see the moment you open the car's hood.

If left in its original condition, it is not something you want them to see. Windshield wiper bays looked terrible, even when these cars were new. Add decades of use, weather, and dirt, and the problem only worsens.

If you own a C3 Corvette, you know how important it is to keep your car in pristine condition, especially if you want to take it to shows and cruise-ins.

And the wiper cowl is no exception. This area not only adds to the aesthetics of your car but also protects the windshield wiper transmission from deterioration caused by the sun and water.

In this how-to video, I will show you how to completely detail the wiper bay to better-than-new condition. This will enhance the look and value of your C3 Corvette.

Whether you are a seasoned car enthusiast or a beginner, this guide is a must-watch for all C3 Corvette owners. So, sit back, relax, and enjoy the C3 Corvette Wiper Bay Cowl Restoration Guide.

Thank you for watching! 🙂👍🏻

DISCLAIMER: Even though I like to wrench on my C3 Corvettes and most of my videos are of a how-to nature, I am not responsible nor liable should you decide to follow my musings on the subject.

The repairs and other work I do are for my own benefit and entertainment, and even though my videos may appear to give technical how-to advice, that's not my intention.

Working on a vehicle is inherently dangerous. If you're not confident, qualified, or lack the tools to do the job correctly and safely, hire a licensed mechanic.
