      Video Review & Installation

      Hey, guys. Adam here with, and today we're taking a closer look at and installing the Hurst Quarter Window Louvers, in the pre-painted option, available for the 2015 and newer Fastback S550s. You should be checking this out if you're the owner of a new S550 and you're looking for a modern spin on a very classic part that we see on some of the older muscle cars from the '60s and '70s. This part here is a three-slot louver design from Hurst, which I think adds a nice, aggressive muscle car styling to the side profile of these newer vehicles. Now, these are painted in-house at AmericanMuscle, using all factory paint codes. So, on the product page, you actually get to select your own paint code. In this case, it's CY for Competition Orange, there's PQ for Race Red, so on and so forth. So, it's painted to match exactly to the factory Ford colors. All of the '15 and newer Mustang colors are available.Now, these are constructed out of a durable, yet lightweight ABS plastic. It's impact-resistant. It's not gonna crack, fade, or otherwise brake, on or off the vehicle. They're applied using 3M automotive bonding tape, which is specifically meant for use on the exterior of vehicles. So, it's gonna last the lifetime of the part. Now, on the backside of that ABS construction is gonna be slots for 3M automotive bonding tape, which is what you're gonna use to adhere this to your quarter windows. Now, 3M automotive tape is specifically made for the use on the exterior of cars, so you know it's gonna be weather-resistant and heat-resistant, and hold up all year round regardless of your climate. And that's something I personally really like about it. There's no glue, there's no nonsense, there's no drilling, modifications required, it goes right onto the exterior.Now, these are coming in at right around 300 bucks for the pair, and you can get it for your S550 with an extremely easy install, you can do it by yourself in the driveway at home. I'm gonna give it one out of three wrenches on our difficulty meter. You can tackle it in about 30 minutes or less. The only tool you're gonna need is a pair of scissors, or snips, to cut the roll of 3M to the size of the backing. I'm gonna show you guys every step of the process, and you can even use adhesion promoter if you want some added peace of mind. Keep in mind, guys, we're gonna be skipping the adhesion promoter for this process, simply because, right after the video, this is going back to stock, so we wanna be able to take it off easily. I'm gonna walk you through everything. So let's get to it.Only tool used in this install include a pair of snips, wire cutters. You can also use a knife or a box cutter, something to cut the 3M tape roll.Well, guys to kick things off here, what I'm gonna do is take our passenger side quarter window louver, put it on our table here on top of the foam padding that comes in the box. I like to do this simply because, when we flip it over, I don't wanna scratch that new paint on our table. So, what we're gonna do is keep this face down, and expose these little notches where our 3M is gonna apply. What we wanna do first before we do anything is grab alcohol wipes included in the kit, crack them open, and we're gonna wipe down the strips where the 3M is going to sit. We wanna make sure we're cleaning off any dirt, dust, debris, really, anything that would prohibit the 3M from getting a good bond. We're gonna clean that off, make sure we have a nice clean surface.All right. At this point, what we're gonna do is take our 3M, and we're gonna unroll it and cut it to length for each one of these sections. Now, these are pretty much the same size, this one's a little bit longer on the corner, so we'll focus there first. Just unroll it, get an approximation, it doesn't have to be exactly perfect, you just wanna get it to about that size. Once you have that cut, lay the strip down right on that little platform there. You're gonna press down and make sure it gets a good. Now, you're basically just gonna repeat this for the rest of them. There are five more, six in total.Now, for the cutting, I'm using these wire cutters, you can use scissors, a box cutter, a knife, really, anything that you have on deck that can just cut through it. It's not too hard to cut through. Another thing you can keep in mind, if you would like, there's adhesion promoter included in the kit, you can break this open, and it's essentially a little yellow sponge. If you are gonna use this, I'd recommend using latex gloves, or some kind of gloves, because it does get very tacky. You can apply that underneath of the 3M tape before you put your 3M tape down. That way it gets a little bit more of a semi-permanent bond, and might give you a little bit more peace of mind. You can also do that on the vehicle, on the window here, when you're applying it there. We're not going to use adhesion promoter, as you can see, simply because, after this video, our vehicle is going back to stock, so we wanna be able to easily remove it. The adhesion promoter makes it a little bit harder to take off.All right. At this point, you can go in and take the backing off of all of the strips, you're gonna peel up on it. You can also use a little knife for this, if you need to. I don't really have fingernails, so it makes life a little harder. All right. From here, we're just peeling these guys off once you get them lifted up. Once the backing is off, what we're gonna do is take another alcohol wipe in the kit and clean off the edges of our window. That way we get a good bond. And again, you can use that adhesion promoter if you'd like, but we're gonna skip over that.All right. So, we got another one of our alcohol wipes. I'm gonna clean off the edges of the window, where that's going to apply, and then work my way through the entire thing. Now, there are multiple wipes included in the kit if you need a little bit of extra. All right. So, we got that dirt and dust off. What we're gonna do is line up our louver, push it into place.All right. So, we're gonna take our louver and use the edge of that glass, and this little curve here, to line this up into place. All right. Once you have it where you like it, you can press down, make sure the 3M gets a good bonding. All right. Once you have that in place, and you like where it's at, repeat this exact same process for the other side.Well, guys, that's gonna wrap up my review and install for the Hurst Quarter Window Louvers, available in the pre-painted option, for your 2015 and newer Fastback Mustang. If you wanna get this for yourself, they're made and painted right here in-house at
