that's exactly why you dont want to have the type of bra you got. all that sand and crap gets under it especially when driving in the rain (look at the inside of the bra when you take it off after it rains) and you will never put it back on.

As for larger stones, this also not true with the new higher quality clear films that are currently used. IMHO

 

Got my clear bra from Premier. I will never turn back to the leather bras. www.premiermobilegroup.com
