3M vs bra

[knuk]

Any input on a bra vs the 3M product? I would prefer a bra as I only want the protection on the track and the highway as this is where I seem to get the "sandblasting" and rock chips. I have heard that a bra may damage the paint, does damage occur if the bra is only used for short periods of time? Like I mentioned, I would only use it for short periods - it will not be left on the car.
I will appreciate any comments.
