      Video Review & Installation

      Hey I’m Justin with, and I’m checking out MMD’s pre painted quarter window louvers fitting all 99-04 Mustangs, MMD is an industry leader that continues to product all kinds of styling parts, that can dramatically improve the attitude of any Mustang. Ok, so these louvers are totally unlike anything else for the New Edge Mustang, whereas a traditional louver design usually incorporates more of a GT500 or fastback style, these windows were designed to fit perfectly into the quarter window openings. The end result, as you can see with our 2000 GT, is actually pretty cool, and I will say works surprisingly well on these cars. The louvers themselves are constructed using a durable ABS plastic and then sprayed right here at headquarters, since these parts are sprayed here using the same base and clear coat Ford uses in their factory, you can expect a perfect color match on your ride. Ok, so we know the louvers are designed to improve your exterior appearance but what about the interior? Well unfortunately the result isn’t quite the same, as you can see the back of the louvers typically have a little bit of overspray and just generally aren’t that nice to look at. That’s why we offer some blackout quarter window decals. These decals are designed to improve the business side of things, making for a clean look inside and out. The best part is, these louvers install easily without the need for any drilling or messy Bondo. If you do decide to go with those quarter window blackouts you will need to install them first using a spray bottle filled with a soap and water mixture and the included squeegee. Once the decals are in place go ahead and clean the area with the supplied alcohol prep pads, once that alcohol is dry grab the 3M adhesion promoter, and wipe it down along the edges where the 3M tape will go. This is a very important step because basically it’s going to ensure a nice secure bond between the louvers themselves and the quarter window. Once that’s done, simply remove the protective backing on the preinstalled 3M tape, and adhere the louvers carefully to your ride, getting all this done should only take you 30 minutes but if you are installing those quarter window blackouts in addition to the louvers, just leave yourself about an hour. So if you’re looking for a totally unique louver option for your New Edge Mustang, all with the convenience of a pre painted part, then you have to check out MMD’s quarter window louvers available right here at

      Hide The Ugly. 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. SEC10 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. SEC10 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 SEC10 quarter window blackout decals are designed to fit all 1999 to 2004 Mustang coupes, including the V6, GT, and SVT Cobra models. They look great combined with louvers or by them-self.
