Industrial-strength windshield protection, laser-cut for the Grenadier. Think of it as a screen protector for your windshield — take a rock strike, peel the layer, keep driving.
Industrial-Strength Protection from Rock Strikes
Gravel roads, trail drives, highway flying debris — the Grenadier windshield takes hits. Windshield Defense is a three-layer polyester film that absorbs the impact before it reaches your glass. When a layer gets chipped or pitted, peel it off and you have a fresh layer underneath. No shop visit, no replacement glass, no insurance claim.
Originally developed for IndyCar® racing — where windshield protection isn't optional — now available for your Grenadier. Same technology, same protection, same peel-and-go convenience.
Fits: INEOS® Grenadier® — Model 1924, Station Wagon, and Quartermaster™ (2022–present). Laser-cut to OEM windshield dimensions for a perfect fit.
Three Layers of Protection in One Installation
Install once, get three lives. Each of the three laminated layers is a full, independent shield over your windshield glass. When the first layer takes damage:
Peel the top layer from the corner
A fresh, undamaged layer is revealed
Repeat when needed — up to three total replacements before reinstalling
Each layer provides 6+ months of protection under normal driving conditions. Heavy off-road use may vary.
Clear, UV-Protected Views
Crafted with optical-grade materials — no haze, no tint, no distortion. Just clear visibility with 99% UV protection built in.
Race-Tested, Adventure-Approved
Initially built for the high-speed demands of IndyCar® racing, now trusted by Grenadier owners who take their rigs off-road. When it's good enough for professional racing, it's good enough for the trail.

FAQ
Will this actually protect against rock chips and cracks? Yes — Windshield Defense absorbs rock strikes and debris impacts that would normally chip or crack your glass. The film takes the hit instead of your windshield.
How long does each layer last? Approximately 6 months per layer under normal use. Heavy off-road or highway driving may reduce that. When a layer is noticeably damaged, peel it off and the next layer is ready.
Does it fit the Station Wagon and Quartermaster? Yes — fits all INEOS® Grenadier® variants: Model 1924, Station Wagon, and Quartermaster™ (2022–present).
Does it work on Gorilla® Glass? Yes, and it's recommended. Gorilla Glass can still chip from rock strikes — Windshield Defense adds an extra layer of protection on top.
Can I install it on a damaged windshield? We recommend installing only on undamaged, OEM windshields. Prior chips or cracks may become more visible under the film.
What's the professional install rebate? If you choose to have Windshield Defense professionally installed, you can submit for a $25 Visa gift card rebate after installation. DIY installation is perfectly fine — the rebate is just a bonus for those who prefer a pro install.
