I was thinking of getting a bra for the front of my insight and I seem to recall that someone here modified their bra to cover the lower air intake area with matching black material. I believe they said they used rivits of some kind or buttons. I'm wondering what buttons or rivits could be used to secure the air block flap to the bra? I can't seem to find something that would work, perhaps I just don't know what I'm looking for. Thanks.
