      Hide The Ugly. Pre-painted quarter window louvers or scoops look awesome from the outside, but not so great from the inside of your ride. That is where a set of Quarter Window Blackout Decals come into play, they will hide the ugly back side of the louvers that weren't meant to be seen by human eyes.

      Aggressive Custom Styling. Even if you don't have quarter window louvers you can still give your Mustang a more aggressive appearance with just a set of Quarter Window Blackout Decals. These matte black vinyl decals simply apply to the exterior of your Mustangs quarter window glass for aggressive custom styling.

      Perfect Fit Guaranteed. AmericanMuscle Graphics vinyl designs have been test fit, refined, and tested again on our very own fleet of vehicles to assure a perfect fit every time.

      Wrapping Cast Vinyl. AmericanMuscle Graphics uses only the highest quality 4 mil Wrapping Cast Vinyl available on the market today. Featuring a built-in protective clear coat layer this wrapping cast vinyl is designed to last at least 8 years of harsh outdoor weather. Making it far more durable than our competitors cheap, calendared vinyl film which starts to degrade in just a couple of years!

      Air Release Technology. Air release technology features miniature air channels on the adhesive side of the vinyl that allows air to easily be squeezed out from under for a bubble-free installation and a smooth wrinkle-free surface.

      Application. These high quality AmericanMuscle Graphics quarter window blackout decals are designed to fit all 2015-2020 Mustang Fastbacks, including the V6, EcoBoost, GT and GT350 models. They look great combined with louvers or by them-self.

        Kinda Different but tough

        Probably better for louvers but I don’t like louvers. They are too 80’s looking. You can’t see through these so say goodbye to your blind spot window.

        I used this to adhere my rear window scoops and it went on smooth and easy! The scoops are holding tight and you can't see the unfinished back of the scoops from inside the car! Perfect product!!

        Looks great. Price is right.

        These are really great first step if you’re going to add louvers later they keep the ugly side looking good as viewed from the inside

        Window Blackouts

        Before putting these on I had ZERO experience with any type of decals. It’s was so easy! Took a little patience to work out the bubbles and get it lined up right (I’m a perfectionist). But I probably had them both done in about 45 minutes tops. And it looks awesome.

      Questions & Answers (10 answers)

      5 Top Rated Questions

      Do you attached the louvers directly to the black out or does it get trimmed back to allow the tape of the louvers to attach to the glass?

      • When installing the louvers to the blackout panel, you would not need to trim the tape when you louvers to them. They can be applied directly to the blackout itself.

      Helpful (3)

      Can these be used on the "inside" of the car, reversing the left for the right, etc.?

      • This should not be installed on the inside of the vehicle as the adhesive settles against the surface of the window which could create a very unappealing look from the outside looking in.

      What’s the best soap to use? Would dish soap be ok?

      How easy are these to remove after being installed? And how would you remove them?

      • The easiest way to remove this decal would be applying mild heat to help soften the adhesive.
