If you want the long-lasting durable protection you get from a ceramic coating, Drexler Ceramic Glass Coat will keep your vehicle’s windshield dirt and water-free. Price and overall value are something else you want to consider when your searching for the best windshield water repellent.

You’ll notice that there are differences in each of these products. Some come with budget-friendly prices, while others are more expensive but give you longer coverage. Think about your driving patterns and what you need from a water repellent before you make a final purchasing decision.
Ease and of Use
Even the windshields on compact cars can look overwhelmingly large when it’s time to apply a water repellent. Since the goal is to cover all of the glass, it helps if the product is easy to get on the glass.
Some repellents are applied with a cloth, which can be a hassle. Depending on the vehicle’s size, you’ll probably need a stepladder to reach the top. Sprays are easier and faster to apply and you may not need a ladder.
Easiest to Apply: Rain-X Original Windshield Treatment Glass Water Repellent
You don’t want to find yourself reapplying the water repellent every few weeks or days. Not only is it a pain, but you could also get stuck in a rainstorm only to find the product has worn off. Now you’re dependent on your wipers to keep the windshield clear.
Even though all water repellents coat the glass, some are better than others. Ceramic coatings are durable and last longer, sometimes for a year or more. The durable coating has another benefit, it also protects the glass from cracks and scratches.
Best Long-lasting Protection: Drexler Ceramic Glass Coat
Price and Overall Value
Water repellents for windshields come at a range of price points. You can find expensive products that last for over 12 months, but you’ll also pay more. If you do decide to spend the money, check to see if the product also repels dirt and snow. It should also create a protective barrier that prevents nicks and scratches.
There are less expensive products that protect your glass from the elements, along with acting as a water repellent. Most are easy to apply, though you will have to do it more often than with most higher-priced ones. However, if you’re on a budget and still want to keep your windshield clean, a cheaper product will do the trick.

PPG Industries Aquapel Glass Treatments Review
Aquapel Glass Treatments are easy to apply to a clean, dry windshield. You can also use the packets on mirrors, windows, and sunroofs. Once the liquid is applied, use a clean cloth to evenly coat the glass. Wipe the repellent off once the windshield is completely covered and you won’t have any problems with visibility in the rain.
The product uses fluorinated compounds to bond the liquid to the glass so water beads and rolls off the windshield. With proper coverage, the product will last for several months, but its longevity depends on the conditions when it was applied. Temperature matters, along with humidity. It shouldn’t be used if the temperature is below 50˚F or above 90˚F.
- Fluorinated compound
- Easy application
- Repels snow and rain
- Glass treatment can only be applied during optimal weather conditions
Aquapel Glass Treatment Review
Manufactured by PPG industries, Aquapel Glass Treatment also uses a fluorinated formula to bond to the vehicle’s windshield. Since it isn’t silicone-based like many combination glass and water-repellent products, it will last longer even through frequent storms and car washes.
The single treatment formula is simple to apply. After covering the glass, wipe the product off with a paper towel or soft towel. Weather can be an issue during application.The liquid won’t seal to the glass if it’s too hot, cold, or humid outside. One application, if done correctly, will last for 6 months or longer.
- Improves visibility
- Easy application
- The liquid is a little more difficult to apply and can only be done in ideal weather conditions

Using nanotechnology, Drexel Ceramic Glass Coat is tough, durable, and long-lasting. One application on your windshield can last for over a year. It’s safe to use on all glass surfaces, including mirrors and side windows. You can also use the coating on a glass car roof.
The product is easy to apply. Temperature isn’t a concern, as long as it’s above freezing and below 90˚ F. Once the product’s applied with a clean cloth, you’ll notice a visible shine on the glass. You’ll be able to see clearly out the windshield whether it’s raining or snowing. The coating also makes the glass a breeze to clean.
