      Review & Installation Video

      Hey I’m Justin with and I’m actually checking out a very versatile piece of vinyl that can serve a couple of different purposes. I’m referring to our matte black quarter window blackouts from AmericanMuscle graphics, fitting all 2010 and newer Mustangs. These panels were originally intended to be used behind certain window scoops or louvers, because lets face it, even though the outside of these scoops look great, the same can’t be said of the inside where overspray and 3M tape are clearly visible from the interior, as a result, the gang over at AmericanMuscle graphics came up with these panels as a solution. As I mentioned earlier, this panel isn’t just good for covering the ugly side of a scoop or louver, as more and more people started picking this panel up they started to realize, hey, this thing looks pretty damn good on its own, making this vinyl equal parts functional and stylish. Just because this vinyl was originally intended to be hidden behind a scoop, or louver, doesn’t mean we cut any corners with the material, all our AM graphics are designed using the highest quality premium cast vinyl, which is by far one of the best vinyls available on the market today. So if you are one of the folks who are just going to rock these panels on their own, you can rest easy knowing that they’ve been designed to last for years on your ride without fading or peeling. Install wise, this one is a total breeze, you’ll first want to spray the window down with a mixture of soap and water, lay the vinyl into place, and then smooth it out with the included squeegee. We do call this one about an hour on the site, but don’t be surprised if you get it done a little sooner. So whether you’re trying to cover the rather unattractive backside of a quarter window louver when installed, or you just like the look of the vinyl on its own, you’ll have to check out these quarter window blackouts available right here at

      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.

      Superior Quality Materials. AmericanMuscle Graphics uses only the highest quality Premium Cast Vinyl available on the market today - designed to last at least 8 years of harsh outdoor weather. It's far more durable than our competitors' cheap, calendared vinyl film which starts to degrade in just a couple of years!

      Application. These high quality AmericanMuscle Graphics quarter window blackout decals are designed to fit all 2010 to 2014 Mustang coupes, including the V6, GT, BOSS and Shelby GT500 models. They look great combined with louvers or by them-self.

        Follow the directions and you should have n problem. My one suggestion is to apply it to a cool surface. The vinyl will stretch and bubble if the surface is warm. Apply it in the shade or garage. Spray the soap/water combo freely, it will squeegee out upon application.

        Always install before louvers

        Bought these to install over my back windows so that when i put the louvers on water droplets don't show from the inside out. These are made of the FINEST quality, very thick and sturdy very happy with the blacked out finish underneath the louvers

        Didn't stick come winter time. Ordered a new set and had it installed at a local body shop. Twice the price, but twice the quality.

        Quarter Window Blackouts

        I was going to just have my wife make these with her Cricut Machine. Took her too long and just easier to order these and install. They were very easy to install and look nice on the car just by themselves.

      I'm confused, I think... Am I missing something? These seem to look exactly like the MMD flush style Quarter Window pieces. The description is also similar. Yet these are 150 bucks cheaper...what's the deal here? Obviously I would just buy these if I wanted this style because I can't see or haven't read a difference from the more expensive pair. So what's the deal?

      • The MMD GT350 Style Painted Window Covers are made of ABS and are pre-painted to match your Mustang paint job. These Quarter Window Blackouts are made of Premium Cast Vinyl and comes in the Matte Black color. They both cover the quarter windows, but use two different materials and finishes. Hope this helps!

      Can these go through a drive through Car Wash?

      • We do not recommend using drive through car washes with these installed.

      Are these safe for a drive thru car wash?

      In one response it is suggested to use these to hide the backside of the louvers. In another it is suggested to use either the black out or louvers but not both stand on the window/ Am I understanding this correctly?

      • TheAmerican Muscle Graphics Matte Black Quarter Window Blackout can either be installed with louvers to hide the back side of the louvers or installed alone to black out your quarter window louvers. The blackout is designed to be installed on the outside of the window but can be installed on the inside of the window with trimming as the inside dimensions of the window area are smaller than the outside. 

      Helpful (0)

      Why can't they be installed on the inside? I already have louvers that came from Ford. I want to hide the inside of the louver. Just use the left side on the right and right side on the left.

      • You should be able to install these Matte Black Quarter Window Blackouts on the inside of the quarter windows, but they may require some trimming since the inside dimensions of the window are slightly smaller than the outside dimensions.

      Question about Quarter Window Blackout Decals I'm considering purchasing a set of Quarter Window Blackout Decals for my 2012 Boss. Two questions: 1. How easy is it to remove the decals if / when I want to bring the Boss back to stock condition? 2. After removing the decals, what condition will the glass be? Will the glass look original or will there be residue that I won't be able to remove and / or will the glass be "etched" by the adhesive? Thanks! 1 answer
