Default Engineered a dash mat that eliminates windshield reflections

Finally, was able to build successfully a dash mat that removed the need of polarized sunglasses. No more windshield reflections anymore!

That looks really good!

How did you build that? Can you add more pics?

Is the reflection with that color really that bad?? I have the saddle and don't notice any reflection at all but I bet that light color would be much worse.

Its a shame to have to do that though...

First, I ordered a third party mat and assesed the problem. This mat had openings in the vents which caused bad reflection in that areas. Also, it was way too shiny as you can see in the first two attached pics, and it had bad creases and fit problems that needed to be fixed.

Then, I applied several coats of a special anti-reflective black cloth paint that is commonly usef to avoid optical reflection in screen projector surfaces. Found an outfitt in Canada that sold this incredibly black carbon-based paint.

For the vent openings, I glued pieces of see-through spandex-based black velour that I found on Amazon underneath the matt. It provided excellent air flow transmission at the same time as good optical anti-reflection characteristic.

To test it, I positioned the car at around noon on a sunny day and parked it in an angle for a worst case reflection and took the next two pics, with and without the mat. The improvement is obvious.

After solving the optical engineering problem, decided to work in the estetics. Didn't like that the aftermarket mat I got extended over the outer leather section of the beautiful beige dash and decided to trim it. Before, I had noticed that the reflections of that section were way up above the windshield area and didn't obstructed my view at all, so I went for it. As you can tell it was a good decition. The next pic shows how the dash looked before the final trim. And the last pic shows a night view of how nice the mat matches perfectly the color combination of my car.

Finally, the mat is pitch black and a pleasure for the eyes in all driving light conditionw, night or day.

Enjoy!

Yes it is. But I am very happy now. What I noticed is that it was not mainly an issue of the color of the dash, but the optical reflection quality of its surface. Regardless of the color, a glossy surface tended to reflect more light. I proved this theory when the dealer gave me a Ceyenne loaner. The Cayenne had a black dash and it also reflected badly at certain angles and light conditions as you can see in the atrached pic.

Very interesting and lucky you that you don't have this problem with your saddle dash. Is it all leather?

Yep, it's all leather.. maybe I just don't notice it, but honestly it's never been an issue.

Yes, it could be the leather. Much less glossier than plastic, as in that Cayenne loaner, I guess. Happy driving!

Thank you @windblow , as time passes by, I like it more and more. In adittion of not getting reflections at all I love the look of it. My wife says it gives it a touch of personality and originality like a set of old ragged jeans. I agree :-)

PS. Bet somebody is getting fired at Porsche. I am sure they don't allow a single bit of reflection, in all light conditions, on their #1 and #2 LMP1 endurance racers ;-)

Have you noticed that Porsche has added a note to the Confusilator regarding dash reflection?

"A word about interior color choices:
Glass is reflective. Certain lighting conditions may cause a lighter color dashboard to produce a noticeable reflection on the inside of the windshield. To make certain that you are satisfied with your selection, ask your Porsche dealer to arrange a test drive experience in a variety of conditions, including with use of polarized sunglasses."
