The Bras where originally used by high end sport car manufacturers to protect the paint on new cars while being tested, and some photos where published and then the trend started.
They are great to protect the front from small rocks and debree, they have a problen when left on the vehicle for to long, specially when it rains or there is condensation that runs down under the Bra, when the sun heats the Bra the temperature can get hot enough to boil the moisture, and over time the paint is cooked, a neighbor had a Porche 911 and one day he was going to was the car, took the Bra off and we could read the word porche on the dicolored paint where the Bra had cooked the paint.
If you are thinking of a complete cover for the entire vehicle, there are several manufactureres and can be found at stores that sell auto parts.
