Diy Plastic Windshield Tinting: A Step-By-Step Guide

how to tint a plastic windshield

Tinting a plastic windshield offers several benefits, such as blocking UV rays, reducing solar heat and glare, and enhancing privacy and style. However, it is essential to consider the regulations and laws regarding window tinting, which vary across different states. Standard tint film is not suitable for plastic windshields due to the risk of bubbling and adhesive-related issues. Instead, specific vinyl products designed for plastic surfaces can be applied to the outside of the windshield, providing a bubble-free, scratch-resistant, and durable solution. Alternatively, some motorcycle owners opt for spraying the windshield with flat black paint, though this is not suitable for visibility.

Choosing a tint film

Legal Compliance

Before choosing a tint film, it is crucial to check the regulations in your state or province. All states have restrictions on tinting applied to front windshields, and laws often vary widely from state to state. For example, Vermont, New Hampshire, and New Jersey prohibit any aftermarket tinting on the windshield and front side windows. The legal tint limit is typically given in terms of the VLT (Visible Light Transmission) percentage, which indicates how much light can pass through the glass. The lower the VLT percentage, the darker the tint. While most states require a VLT of 70% or higher for front side windows, the front windshield usually requires a VLT of 80% or more.

Purpose

Think about why you want to tint your plastic windshield. Are you primarily interested in blocking UV rays, reducing solar heat and glare, enhancing privacy, improving aesthetics, or a combination of these factors? Different tint films offer varying levels of visibility, privacy, heat reduction, and UV protection. For instance, a 50% VLT film provides ample sun protection without compromising visibility or privacy. On the other hand, a 20% VLT film offers a high degree of privacy and sun protection but reduces visibility, especially at night.

Type of Tint Film

There are several types of tint films available, including dyed, carbon, metallic, and ceramic. Dyed films are the most affordable option and block sunlight by absorbing solar heat. Carbon tint films provide a matte finish, enhance shatter resistance, and effectively block UV rays, preventing fading and protecting the car's interior. Metallic tint films use tiny metallic particles to reflect light and reduce heat, but they may interfere with GPS, radio, and cell phone transmission. Ceramic tint films are the most expensive option, offering maximum visibility, exceptional shatter resistance, reduced glare, and effective UV protection. They do not interfere with electronic transmissions and can block up to 50% of solar heat.

Installation

Consider whether you will install the tint film yourself or seek professional installation services. Installing a tint film yourself may be challenging and could damage your windows if not done correctly. Professional installation ensures a perfect fit and can save you time and money, especially if you need to remove an old tint film. Reputable window tinting companies are familiar with the regulations in your area and can help you choose a tint film that complies with the law.

Preparing the plastic windshield

Firstly, it is important to choose the right location for the job. Ideally, you should work in a garage or a shop, but if that is not possible, find a shaded area away from wind and dust. Make sure there is enough room to fully open the vehicle's front doors. It is also recommended to put down tarps or plastic sheeting to speed up the cleanup process and prevent damage to the interior of your vehicle.

Next, gather all the tools and supplies you will need, including window tint, a body filler applicator or squeegee, a soap and water solution, and a utility knife. It is also important to wear protective equipment, such as a facemask, safety glasses, and gloves, to ensure your safety during the process.

Before you begin tinting, it is crucial to prepare the plastic windshield surface. Clean the windshield thoroughly to remove any dust or debris. If you are working with acrylic (plexiglass), remember that it has static properties, so it is recommended to spray the back side of the object with cold water to reduce static and attract less dust.

Now, you are ready to cut the tint to fit your windshield. Place the window tint on the inside of the windshield and tape it in place with masking tape. Cut around the edges to get the basic shape, and then use a utility knife for precise trimming. It is important to work quickly as applying window tint can be tricky.

Once you have the basic shape, remove the clear plastic protective film from the adhesive side of the tint. Keep the tint and the inside of the windshield wet by spraying them with the soap and water solution. This will prevent the tint from collecting dirt and sticking to itself.

With the tint still wet, carefully place it on the inside of the windshield, ensuring it is centred and aligned correctly. Use the squeegee to smooth out the tint, working from the centre outwards until it lays flat on the windshield.

Applying the tint film

Firstly, it is important to note that standard tint film cannot be used on plastic windshields as it will bubble and the adhesives may etch the plastic. Instead, you should use a vinyl product, made specifically for plastic surfaces. These can be found at your local sign shop or online.

Before applying the tint film, find a suitable location to install the tint. This is usually in a garage or a shop, but anywhere shaded and away from wind and dust will work. Make sure there is enough room to fully open the vehicle's front doors.

The tint film should be cut on the outside of the windshield, with the adhesive side facing upward. Lay the tint with the adhesive side facing the sky; the adhesive side will have a clear plastic wrapper, which should be removed before transferring to the inside of the windshield.

Spray the adhesive side of the tint with a soap and water solution, then spray the inside of the windshield. Place the tint on the inside of the windshield, with the adhesive side still facing upward. The tint should be relatively close to where it will sit. Then, beginning in the center and moving outward, squeegee the tint until it lays flat on the glass surface.

Once the tint is in place, you will need to remove any air bubbles. Air bubbles are bound to happen when applying window tint. To remove them, poke the bubbles with a safety pin, using only one hole per air pocket. Then, spray the tint with soapy water and squeegee the window, pressing the air bubbles toward the holes you made. The air will escape through the holes.

Removing air bubbles

Bubbles are a common issue that can occur during the installation of window tinting or develop over time due to factors like temperature changes, improper application, and environmental pollutants. Here are some detailed, step-by-step instructions to help you remove air bubbles when tinting a plastic windshield:

Identify the Cause

Before attempting to remove the air bubbles, it's important to identify the cause. Bubbles can form due to various factors, including improper installation, temperature changes, environmental pollutants, and inadequate preparation of the window surface. Understanding the cause will help you choose the most effective removal method.

Prepare Your Tools and Work Area

Gather the necessary tools for removing the air bubbles, such as a squeegee, hard plastic card, or a pin and iron (if you prefer the ironing method). Ensure your work area is in a shaded area away from wind and dust, with enough room to fully open the vehicle's front doors.

The Squeegee Method

If you have visible air bubbles, you can use a squeegee or hard plastic card (such as a credit card) to gently scrape them out. Carefully apply pressure and glide the tool across the surface to push the air bubbles out to the edges. Be cautious not to apply too much pressure, as it may tear the tint film.

The Ironing Method

An alternative method is to use an iron set to a low temperature. First, use a pin to create tiny holes in the tint film over the air bubbles. Then, gently run the iron over the area to press the bubbles out. Ensure the iron is on a low setting to avoid damaging the film.

Prevention for Next Time

To prevent air bubbles in the future, ensure the window surface is thoroughly cleaned and prepared before applying the tint. Remove any dirt, dust, or debris, as these particles can create air pockets and cause bubbles to form. Additionally, choose high-quality tint materials to reduce the likelihood of bubbling and other issues.

Remember, if you feel uncomfortable performing these steps yourself, you can always take your vehicle to a professional tint shop for assistance.

Drying the tint film

Before beginning the drying process, it is essential to prepare the work area. Choose a location that is away from wind and dust, such as a garage or a shaded area. Ensure that you have enough room to fully open the vehicle's front doors. It is also important to gather all the necessary tools and supplies, such as a body filler applicator or squeegee, a soap and water solution, and the tint film itself.

The tint film should be cut to the shape of the windshield on the inside of the vehicle. When cutting the tint film, ensure that the adhesive side is facing upward. Once the tint is cut to the correct shape and size, it's time to move on to the drying process:

  • Begin by spraying the adhesive side of the tint film with the soap and water solution. This step is crucial as it ensures that the tint film can be adjusted and moved into the correct position without sticking prematurely.
  • Spray the inside of the windshield with the same soap and water solution. This will help the tint film slide into place without sticking or leaving residue on the windshield.
  • Place the tint film on the inside of the windshield, centering it as much as possible. The soapy water allows you to make adjustments as needed.
  • Once the tint film is in the correct position, use a squeegee to remove any air bubbles. Start in the center and move outward, applying medium pressure to smooth out the film.
  • If air bubbles persist, carefully poke them with a safety pin, creating a single hole per air pocket.
  • Continue to spray the tint film with soapy water to prevent it from drying out. This is important because a dry tint film will be more challenging to work with and may result in more air bubbles.
  • Use the squeegee to press the air bubbles toward the holes, allowing the air to escape.
  • Reapply the soap and water solution as needed to keep the tint film and windshield wet during this process.

By following these steps, you can effectively dry and apply the tint film to your plastic windshield, ensuring a smooth and bubble-free finish. Remember to take your time and work in a dust-free environment to achieve the best results.
