Can You Use Ceramic Spray on Windshield Wipers, Cowl Panels, and Wiper Arms?

You’re cleaning up around the windshield—wipers, cowl, and trim—and you’re wondering: “Can I use ceramic spray here to protect and restore the look?”

Yes—for most of it. Ceramic spray like Tough As Shell works great on wiper arms, the cowl panel, and surrounding trim—just keep it off the rubber blades themselves.

What Parts Can Be Treated with Ceramic Spray?

✅ Safe for:

Painted or plastic wiper arms
Cowl panels below the windshield
Trim around the base of the windshield
Plastic washer nozzles and vents

🚫 Avoid:

Rubber wiper blades—ceramic spray can cause streaking or skipping
Moving wiper linkages or motor housing covers

Why These Areas Deserve Protection

Wiper arms fade and oxidize over time from UV exposure
Cowl panels trap leaves, dust, and water—a breeding ground for grime
These areas are overlooked during typical waxing or washes

How to Apply Ceramic Spray Around the Windshield

Clean the area first using The Super Soaper
Dry with care using the Everyday Microfiber Towel
Spray Tough As Shell onto a towel or foam applicator
Wipe across the wiper arms and plastic cowl evenly
Buff lightly to prevent high spots or streaks

How Long Will It Last?

Expect 4–6 weeks of protection in these exposed areas. Reapply after each wash or monthly for maximum durability and fade resistance.

Pro Tip: Combine with a Trim Dressing

For an even deeper, darker finish on plastic cowls, apply All Dressed Up first, let it cure, and then top with Tough As Shell for locked-in protection.

Testimonial

Don’t Forget the Windshield Zone

It’s easy to overlook the area around your windshield—but those surfaces take just as much abuse as your paint. Protect them properly and they’ll stay cleaner, darker, and longer-lasting all year long.
