Wind Noise

Interesting, SC believes that PPF on the side mirrors contributes to wind noise. Has anyone else heard this?
Nope. Unless it’s flapping around, I’d tell SC to continue investigating.
 
Said that it changes the speed of the airflow around the mirror. Stated that testing has been done with/without PPF. I was quite shocked to hear this. Not sure I believe it either, but just reporting what they told me this morning. I’m 100% PPF’ed.

I’ve never heard of PPF changing anything like this. Mine are PPF’d and ceramic coated, so they are very slick.

Same. I can’t speak to non-ceramic coated, I suppose.
 
My car is a lease, I have neither ceramic nor PPF. I had no whistle for over a year, then it just showed up one day. No idea what changed, but it wasn't any kind of coating or film.
 
If not already done, perhaps this TSB will solve your wind noise problem. It solved mine.
