Can you do it yourself?

You can do it yourself with a spray bottle, water and a rag. The process is easy and doesn’t take much time. 

Here’s how: 

  • Clean the window as you normally would by washing and drying with a microfiber cloth or paper towel. 

  • Spray the window with water from a spray bottle. You don’t want to saturate the window, just make sure it’s wet in order for the sealant to adhere properly. 

  • Rub the liquid side of the film onto the window using pressure, then use your hands or an applicator squeegee across the entire surface of the glass in one direction. This will cause any air bubbles on top of film to work themselves out.

  • Wait for about 20 minutes for it to fully dry before cleaning with a microfiber cloth or paper towel. If water sticks on top of the film, you can use a squeegee or sponge applicator again in one direction. This process should be done every few months in order to maintain film strength and clarity. 

However, depending on what type of sealant you buy, applying it may be more complicated than expected. It is always important to read the instructions carefully so that  you need to save a hardworking day.

FAQ: Best car glass sealant

Q: What kind of glue is used for car windows?

A:  There are two types of window glues that are most commonly used in cars. One is silicone, and the other is polyurethane. Silicone works well for smaller pieces of glass such as mirrors and side windows, but it doesn’t provide enough adhesion for large pieces like windshields. Polyurethane has the opposite problem – it’s great for large pieces of glass, but not so good on small ones.

Q: How long does car window sealant take to dry?

A: It takes about minimum 10 to highest 20 minutes for the product to be fully dry. However, it can take up to 30 minutes in a humid environment and depending on how hot or cold it is outside. In some cases, you may need to leave the windows open for a few hours in order for them to dry out enough before being able to close them again.

Q: Does 3M adhesive work on glass?

A: 3M adhesive can be used on glass and is a very popular option for window installations. If you are looking for an adhesive that works on both glass and metal, 3M is a great choice. The 3M adhesive comes in various lengths, so you can find the one that will work best for your project. To help you read our review first. 

Q: Can silicone sealant be used on glass?

A:  Yes, silicone is a great sealant for use on car glass. Unlike other types of sealants, silicone won’t cause any streaks on the window. It’s also an excellent choice for vehicles that have been in accidents and require windshield replacement. It can even be used as an automotive adhesive, so it doubles as both a protection and repair agent. There are two downsides to this type of sealant though – it has a shorter shelf life than other sealants and it doesn’t last as long in extreme weather conditions like high heat or cold.
