I live in a rainy area, and if there’s one thing I hate, it’s having my visibility ruined by a grimy, water-smudged windshield. I’d seen a few viral demos of water sliding off glass like magic, all thanks to this so-called “Nanomax Coating Spray.” I was skeptical, but curious enough to try it.
What Is the Nanomax Coating Spray?
According to the brand, Nanomax is a hydrophobic nano-coating spray that forms an invisible, waterproof layer on glass surfaces. It claims to repel rain, dirt, and grime from car windshields and mirrors, promising better visibility and easier cleaning. One bottle supposedly lasts for weeks.
Why I Tried It
Between heavy rains and dusty harmattan, my car windshield constantly looked streaky. I didn’t want to install expensive ceramic coating, and wiping the glass every morning was getting old. For $20, Nanomax seemed like an easy, no-equipment-required fix.
My Experience Using It
The bottle arrived looking like a generic repackaged product, no fancy branding, just a blue and white label. It came with a microfiber cloth. The instructions were simple: clean the glass thoroughly, spray on the coating, wipe it in, and wait a few minutes before buffing.
I applied it one evening after washing the car. The spray had a strong chemical smell, but nothing unbearable. The application was quick, about five minutes for the whole windshield. The glass looked the same afterward, but I noticed less streaking the next morning.
When it rained three days later, water beaded up and slid off faster than usual. It didn’t eliminate the need for wipers, but I barely needed them at moderate speeds. Visibility definitely improved during light and medium rainfall. However, the coating wore off after about a week and a half. Once I washed the car again, it was like I’d never used it.
Pros
- Easy to apply and beginner-friendly
- Noticeable water repellency during the first week
- Can be used on other glass surfaces (mirrors, windows)
- Inexpensive compared to ceramic coatings
Cons
- Short-lived effect (fades after 1–2 weeks)
- Packaging feels generic
- Strong chemical scent
- Doesn’t fully eliminate the need for wipers
Is It a Scam?
No, Nanomax isn’t a scam as it does offer a temporary hydrophobic effect, and for under $25, it delivers on its basic promise. That said, it’s not a miracle product. While Amazon reviews are mixed, the positive ones praise it for short-term clarity during rain, while others complain it fades too fast to be worth reapplying. A few Reddit threads even point out that it’s likely the same as other white-label nano sprays sold under various names.
Where to Buy and Price Point
Nanomax Coating Spray is available on Amazon and the brand’s own site for about $19–$25 USD, depending on promotions. Some sellers bundle it with extra cloths or offer 2-for-1 deals.

Conclusion: Would I Recommend It?
If you’re curious about nano coatings and want a quick, temporary fix for rainy days, Nanomax isn’t a bad place to start. It does what it says, just not for long. Personally, I’ll use it again for quick weekend trips or during rainy seasons, but it’s not replacing a proper windshield treatment anytime soon.
