FRS window/mirror rattle fix

[@percymchow]

Thanks - My BRZ mirrors have a slight looseness like yours did. I chalked it up to crappy workmanship, but loose screws. Sheesh. I think maybe backing them out and getting some Loctite on the threads will help in the long run eh?

Use your girlfriend nail paint/lack *just a little bit* on screw threads and let them dry. Than screw again and will work like magic.
