How to Tint Rear Window With Defroster


Window tinting is one of the easiest and fastest ways to give your vehicle a customized look. It also darkens your interior, which helps in reducing glare from the sun. Window films work by blocking ultraviolet rays that can fade fabrics and cause skin cancer. It keeps interiors cool while making them darker, preventing eye fatigue, and making it more comfortable for you when driving at night or in bright light conditions.

Some tint films on the market are even infused with UV blockers that make sure harmful rays do not get through, no matter what kind of weather you’re driving through. Today I am going to discuss how to tint rear window with defroster. So let us get started.

Step-wise Guide on How to Tint Rear Window With Defroster

  • First of all, apply masking tape on the edges of your rear window so that it won’t get dirty, and be careful not to cut yourself while cutting the film with a knife.
  • Place the tint on the top part of your car’s back rear windshield and carefully cut around it with a razor blade or Exacto-knife keeping in mind that you have to leave some extra space for defroster wires.
  • Outline all the necessary holes left around by removing parts needed to allow installing defroster. This is a crucial step as we don’t want to mess it up here! Carefully sand away uncovered areas until complete removal of those areas allows easier installation of both headlight washers and the defroster.
  • Now it’s time to install the film on your back window, stick it carefully with a silicone adhesive from an aerosol can of windshield sealer & be sure to wear gloves because that stuff gets nasty! Make sure you don’t get any bubbles in between. Otherwise, it will look like hell:)  Be patient and take your time when installing tint film because there shouldn’t be any wrinkles if done properly.  Remove any excess adhesive by gently brushing it with a soft cloth.
  • Wipe off the remaining silicone adhesive from around the edges horizontally and vertically to ensure there aren’t any gaps between your window and film. Otherwise, that will cause bubbles.  Apply some pressure on those areas where silicone leftovers are sticking out of:). Finally, carefully apply some soap water around corners & along edges to remove all excess silicone adhesive and let it dry for about 24 hours before using your back window defroster again. Or rather wait couple of days until sides lift up slightly, creating a “bendable” border where it’s easy to get underneath without leaving a sticky residue behind;) Wait until you got a chance to use it as if you leave it until the adhesive is fully cured. You won’t be able to get rid of little leftover silicone.
  • Once you’re done with the edges and make sure that your defroster will work just like before without creating air bubbles on your back window:)  you can remove masking tape off your rear window edges. Okay, now let’s wrap up! After finishing installing defroster wires along with headlight washers, you might notice that there still are a few “holes” left. Well, in case if you want to cover them by applying some vinyl tint film that also covers those holes (or any other type of thin dark film), all we need to do is install a piece of black card stock behind our tinted film to make the holes completely invisible.

Why Tint  Rear Windows Using Defroster?


Tint on windows is a great way to ensure privacy when parked or moving around.   Just imagine how hard it is for someone standing from outside to home. There are kids inside who are watching TV or playing video games without knowing what they are up to.  Grown-ups also need privacy at times, and we think tinted rear windows will come in handy then, too (excess drinking one night?).  By the way, we would advise you not to take this reason as the primary cause of tinting your car windows.


UV ray is one of the biggest enemies of a car’s interior. It causes fading in seats, carpets, and many other parts inside your vehicle (we have covered this topic before). However, you can protect those parts from getting damaged by using window tint film.

Theft Deterrent

Window tinting will also send an extra layer of security signal to potential thieves who want to try their luck stealing your car or breaking into it. We have seen some people using heavy plastic film for rattling purposes, but we don’t think that is a good idea because such material tends to break easily if the burglar puts some force in breaking into your car.


this is probably the best benefit that comes when you are tinting the rear window with a defroster, especially during wintertime or rainy season, because the defroster helps to quickly clear up fog frost and condensation from inside of your glass.  During those times, the rear window heats faster than others and needs extra protection too.

Increases Privacy While Driving

by installing a privacy film on your windshield, not only will people outside be unable to see through it, but they also won’t be able to tell who’s driving the vehicle!  Bonus for women drivers, I would say…

People who are in the business of buying cars can’t wait to see a car with tinted windows.  There’s no way they will leave your vehicle and drive to another parking lot if it has privacy glass installed on all windows. In addition, they definitely prefer window tint over the plastic film for rattling because such films tend not to break easily compared to heavy-duty plastic material.


Window tinting can benefit your car in several ways, and there are no reasons to wait another minute if you want to hide something from the others, improve glass safety or breathe easier during those hot summer days. However, when it comes to defroster installation, we think you might need professional help (or at least someone who has done this before) because it is not as easy job as installing a headlight washer system that most of the users handle on their own.
