Why do watermarks happen and how to prevent it?
Watermarks on a cars paint, especially on black and dark color cars is something very unsightly and drives most of us crazy.
There’s several reasons why watermarks happen, but we’re going to talk about the most common and how to prevent it.
Watermarks can happen if you use a regular water washing method and don’t dry your car properly. When that happens, calcium and other mineral sit on the paint’s clear coat, and sometimes it can etch into the clear coat, creating watermarks.
Another very common reason for watermarks is parking your vehicle next to or to close to sprinklers.
Sprinklers have hard water. Hard water is water that has high mineral content such as calcium and magnesium carbonates.
What causes the watermarks is not the water itself, but the minerals in the water sitting on the paint surfaces and not being washed off.
In some cases, simply washing your car could do the job of removing the watermarks as long as its recent and the paint wasn’t exposed too long to the sun rays.
If the later was the case, than the next go-to should be claying your car.
What the clay does is remove all the contaminants sitting on the paint’s clear coating leaving the paint smooth and contaminant free.
If claying does not do the job, the next option should be getting a one step polish to remove the watermarks.
The best way to prevent watermarks from happening is to apply a sealant or a coat of wax every 2 to 6 months, depending on what you choose to use.
Wax usually gives your car a 2 month protection and a sealant can protect your car up to 6 months, yet, the choice will be entirely up to you.
What the wax or sealant does is it creates a protective layer on top o the clear coat.
Whenever your car is hit by hard water, the minerals in that water will sit on that protective coat and not on the clear coat.
Applying a wax or sealant is the best way to protect your vehicle from getting watermarks.
And as always, keeping your car clean is the way to start.
