Finding the best glass coating for cars isn’t easy—car window protectors seem to be a dime a dozen these days. How do you know which one will truly improve your visibility and make cleaning easier? Well, there’s a few things you can look out for, and we’ve outlined them below. Let’s take a look:
1. Nanotechnology
The best glass coating for cars use nanotechnology. Why’s that? Durability. Old-school products like Rain-X are poly-sealants, a 1980’s technology that while impressive for the time, only last a few months at the very best. The new school, like Dr. Beasley’s Glass Serum Kit, are entirely nanotechnology-based. These nanocoatings (also known as ceramic coatings) are insanely durable and take years to wear off. Plus, they resist grime and bead off water on a whole other level.
2. Durability
Now, just because a glass coating is nanotech-based doesn’t necessarily mean it’s the MOST durable. There are more than a few “ceramic” coating brands out there pushing glass coatings that require bi-yearly re-applications to match their claimed 3 year longevity. Coatings like Glass Serum, however, can last 5 years or more with only the help of a wiper fluid additive.
3. Low sliding angle
So you’ve found a coating that’s nanotech-based and highly durable—great, but what about the sliding angle? This is something we’ve talked about at length here on Behind the Detail, but we’ll give you a quick recap: in order for a water repellant surface to truly shed water, it needs to have a low sliding angle for water beads. Otherwise, rain droplets will just hang around on your windshield, which doesn’t do much at all for visibility. Dr. Beasley’s has some interesting nanotechnology that’s engineered for low sliding angle, and that tech extends to their Glass Serum nanocoating. So be sure to check that out!
Wrapping up
To recap: If you’re hunting for the best glass coating for cars, you’re going to want to ask three questions:
- Is it nanotech-based?
- Does it last longer than three years?
- Does it have a low sliding angle?
If the answer to all these is “Yes”, you’ve got a solid glass nanocoating on your hands. One you may want to take a look at that hits all three of these points is Dr. Beasley’s Glass Serum. They have an even longer-lasting version called Glass Serum Pro, too. If you want to find an installer for those coatings, check out Dr. Beasley’s Authorized Detailer map and see if there’s one near you. They can even get you a 9-Year Warranty on the Pro!
