How Much Does Car Window Tinting Cost in Wisconsin State 

In Wisconsin, the price of a window tint can be as low as £25 per window. On average, you can expect a price tag of $50 per window. For a typical 6 window car, that can result in a price range of $150 – $300 for the total coverage.

How Does Car Window Tinting Work? 

Window tinting film uses a specific type of polyester-based film that allows only certain types of sun rays to come through into your vehicle. The film then reflects or absorbs the harmful rays so that they don’t penetrate the glass and cause harm to you, your family, or the interior of your car. 

The amount of metal, dye, or ceramic within the film will determine how much light is blocked, which is why there are different levels of tint that you can purchase. The lower the VLT percentage, the less light is allowed into your vehicle. 

What Is The Best DIY 50% Tinting Product?

50% window tints are among the most popular and therefore the market is full of high-quality options. However, we have found that the MKBROTHER 50% VLT Professional Window Tint is one of the best you can buy. 

Why Is This The Best? 

This tint from MKBROTHER is offered in seven different sizes, but they all have the same height of 24 inches. This makes it easier for you to cut out the shapes of your windows without wasting a lot of your film. We find this feature incredibly beneficial for beginners who have never added a window tint to their vehicles before. 

The film is 1.5 millimeters thick, made of a premium quality film that is resistant to scratches, peeling, and bubbling. However, the thickness won’t compromise your window mechanisms, meaning that you can still use them effortlessly without damaging your window tint. 

You’ll find that this tint blocks 50% of light and heat from getting into your car. However, up to 99% of UV rays are blocked, keeping you and your car safe from even the brightest of days. 

How To Apply To Your Car 

MKBROTHER offers both instructions on how to apply this film to your windows, as well as illustrations to make it an even simpler process.

Firstly, you’ll need to clean your window as well as you can with a high-quality glass cleaner. Cut the tint to the shape of your window with one inch of allowance all the way around its perimeter. You can also cut the shapes before you begin the application process if you’d prefer. 

Apply the adhesive tape to each side of one corner of the tint and pull them apart. This will separate the clear liner backing from your film.

Spray the adhesive side with the spray solution as well as the inside of the window. Place the film onto the window and remove any bubbles with a flat tool, such as a squeegee. Now trim the edges of the film and you’re done with the first window!

Medical Exemption 

To be allowed a darker tint on your car’s window, you need to receive a written statement from your physician which can clearly identify your medical condition. This medical condition must be connected to light or other relevant factors.

The written statement must also have a justification for the recommendation. It then needs to be confirmed with the local law enforcement to create an affidavit. This affidavit will have your medical needs, physician details, and the law enforcement signature. It will also need the make, model, year, and vehicle identification number of the car in question.

Your permit should then be displayed on your dashboard until it has expired.
