Here are some pictures of the space on the left mirror where the wind blows through and makes the whistling noise. With the tape in place there is no whistling noise at all. So far it has not prevented the mirror from folding and unfolding.
Pictures speak a 1000 words. Thanks !!
I may try some painters tape first and see if I notice any difference. I've been pretty happy but always worth experimenting in case I can do better.
