Side Mirror Aeroacoustical Noise

Before I tried to use touch up paint on vinyl tape, I would use this material:

Meanwhile, used exterior grade tin foil with pressure sensitive adhesive, painted with Automotive Touch up paint.
Several images of the project
Used non-drying modeling clay to fill screw hole pockets.
Modeling clay, stencil, Exacto knife and foil to create screw hole recess covers.
Gently scribe a circle on aluminum foil with template and use scissors.
Automotive Touch up paint brand primer, body color paint and clearcoat.
7/8\" aluminum foil cover plugs painted.
Self-adhesive aluminum covers applied. Paint match very close. Aluminum crinkles easily which required several attempts. Lower profile Aluminum foil will not snag air as would a vinyl plug
Another issue are raised P.N.'s and mold marks...Noisy.airflow here too.

This will require extra work and expense to acquire.
I trust you agree the mirror modifications do not increase NVH...and that by eliminating rough surface areas, especially around turbulent side view mirrors, that aeroacoustical noise will reduce.
Meanwhile, perhaps you can also help me...
I am looking for a correct supplier of seat leather...like the high quality leather that is used in my 1999 LS400.
I understand you can recommend a source.
Thank you

Your request for actual measurements is valid.

Without buying an expensive sound level meter, there are simple and easy ways to measure it using a smart phone.
For examples, these below are the two of actual methods. There are many other applications too and I hope you to add the actual data to your many different experiments.

I always find your experiments very interesting but sorry to say that there lack actual measurement results in the engineering points of view. Of course, human ears are effective to compare sound levels but the actual measurement results by equipments with figures are important for other people who are not working together you.

The newer models have mirrors without; screw holes, raised part numbers or mold marks.
Not planning to perform any testing...as Toyota has already adopted this approach, which I trust is sound...
Meanwhile, what information can you share about leather supplier.??

Contemporary Lexus models have addressed this question....by adopting aerodynamic and more aeroacoustically quiet mirrors.

Regarding the leather supplier, the representative person here was a Mexican gentleman and he said, "No está permitido abrir el nombre".
Sorry that I have no idea to share the company name. The only thing I can say is that their facilities are located in North America.
