What to Use as a Windshield Coating

Porsche 911 Air-cooled Windshield Coating

Let’s take a look at the different things I use for windshield coating when I’m finishing up a detail project on a car.

As is the case with your car’s paint, it’s a great idea to coat your windshield for maximum slickness.

This not only allows your windshield to remain clean longer, but also makes it so that water sheets off when it rains. Your car’s windshield remains slick longer and your wipers don’t have to do as much work.

We all know Rain X. Rain X works as described. It is a great option for a windshield coating for making it slick and keeping it clean. I do use it often and I keep a bottle of Rain X in my car detailing kit at all times. However, I do have one small niggle with Rain X. The one thing I don’t like about it is that it hazes over even after you’ve wiped it off. This just adds to application time as I find I have to wipe it on, wipe it off, and then after a few more minutes wipe it off yet again – with more buffing that I would like. Still a great product.

There has to be a simpler way…

The purpose of this article is to look at other options for windshield coatings. Most of these are a lot simpler than you might think. Yes, a lot simpler.

Here are the two things main things I use as a windshield coating when I don’t use Rain X:

  1. Carnauba Wax
  2. Synthetic Wax.

Haha, see? I said simple. I pretty much coat my windshield with whatever I used to wax my car.

If I’m busy waxing with carnauba wax, such as Meguiar’s Deep Crystal Carnauba I just put a tiny bit of it on the windshield and buff it out like I do with the paint. In fact, it’s enough to simply buff the windshield with the same microfiber towel that I’m removing excess wax from the paint with. The microfiber towel usually has enough waxy residue from the car wax to leave a nice film on it when buffed. Done deal.

The same as above applies when I’m using a synthetic wax. Between synthetic and carnauba there really is not much of a difference in how you would apply it to your paint (or as a windshield coating for that matter).

With the synthetics, there is a product I will often use for a windshield coating. This product is Rejex. I have a full review of Rejex here.

There is one exception to all the above however. More often than not, regardless of what I might be using to wax the car, there is a product I pull out to coat my windshield most of the time. That product is Meguiar’s Ultimate Synthetic Quik Wax spray. The reason I love it for a windshield coating is that it’s very easy to use, very quick and I only have to wipe it down ONCE. In fact, it even goes on with barely a haze.

Just spray a little bit of Meg’s Ultimate Synthetic Quik Wax on a clean, dry, folder microfiber and spread over your windshield. Immediately, flip the microfiber over to the dry side and buff it out. You don’t even have to wait. Go ahead and run your hand over it. You’ll feel how slick the windshield coating feels.

Note that all these products are just a quick way to coat your windshield to make it slick, but none of them last very long. They are really meant for people who wash and wax their cars rather often as you don’t have to worry too much about longevity.

Go ahead and try a bottle of Meguiar’s Ultimate Synthetic Quik Wax wax spray on your windshield. You’ll be surprised at how well it performs. Get it below.
