        How well do they handle the sun and heat in the Nevada and Arizona area?

        • These will be able to hold up great in in the heat and should be able to withstand numerous elements!

        If the MMD lovers can be painted and I assume they are ABS then why do they state that the eg ones are not suitable for painting once I installed these on my black mustang they aren't even close to Matt black look me grey

        • The E&G EGX Rear Window Louvers have a rugged textured black finish which is not generally suitable for painting. In order to paint the louvers, you will need to sand down the surface to a smooth finish in order to properly primer and spray the surface. Due to the length sanding process, we generally do not recommend having the product painted.

        Does the louver keep the inside of the car darker and cooler than before? And can you really see inside of the car with the louvers?

        • The louver will help block out sunlight helping the car remain cooler inside the cabin. At certain angles you will still be able to see inside of the car.

        I am looking at picking up some louvers and really like the looks of these. I am skeptical about the two piece construction and it holding up to the elements and cleaning. Have you washed these in a brushless carwash?

        • The EGX Rear Window Louvers can be left installed in most car washes, however we recommend a 'soft touch' or no touch style car wash to avoid potential damage.

        How likely are they to fade over time.

        • This would depend on the type and amount of exposure. As part of normal detail you can buy product to darken them up.

            Take your Time!

            I would say that using 3M™ Tape Primer 94 is a mandatory step on installation. Two of the applicator pens are included in the kit. This also means you only get one shot to set it down properly! A word of warning, the red tape is like a weld for how strong the bond becomes the moment it touches. I deviated from the install sheet in that I set the louver down on the clean glass and centered it up on all edges with none of the 3M red tape liners removed, yet. Note that the louvers sit way up on the glass and overlaps the top of the roof by about an 1/8". This is necessary to allow the trunk to clear properly when opening it. Check this before exposing any adhesive on the red tape pads so you do not end up with a big miserable problem. When I was certain everything was positioned perfectly, I carefully lifted the top of the louver away from the window enough to allow me to pick the red tape liners off the center mounting. Then I loosened the nut and pushed the pad down on the glass squarely and firmly. This fixes the height for the whole louver assembly - it cannot slip down on you. Carefully, I went top to bottom, and one at a time, removing the 3M Tape liners on a single pad and setting it down firmly until all the mounting pads were affixed to the glass. Lastly, I removed the louvers and used a small poly roller to roll down the tape on all of the mountings. Turned out perfect. The louvers look great! Good Luck with your install.

            I've been looking at all the louvers they offer along with reviews and I went with this one. Most said this was the best looking set and I believe that to be true. They are pretty sharp and good quality

            Easy to install. Looks great on the car. No rattle. Easy to remove for detail work for show. Makes appearance of the car stand out. Does not hinder rear window view. For the money you cannot go wrong with this item. Took about 2 hours to install. Took mine time to get it right...

            Every mustang needs rear Window Louvers

            It really improves the look of the car and freshens it up. Nobody can believe the car is 14(06 born in 05) years old and a daily driver. I have to say it helps to keep the car nice and cool in the sun! This is a 2 piece unit and the fit and look is quite good but not 100 perfect. It is like 1/4 inch too narrow, but only I notice that. Overall very happy with it, we will have to see how it holds up to the MN winters!

            Works like it's supposed to

            I love the louvers, super snug fit and changes the whole look of the car. It doesnt affect your vision at all either which was crazy to me. I will say the one problem I have with it is that it is kinda bowed just a bit in the middle on the bottom edge, so I have to push that down to open my trunk.

            Not quiet right

            Two pieces do not attach correctly. I've contacted American muscle and the told me to try a few things, which didn't work. I have cleaned, heated, tried different types of tape (3m and guerilla) nothing works. The two pieces will not adhere to each other, it is as if there is a 1/8 separation in the middle which keeps pushing them apart.
