Personally I never recommend bras to anybody. No matter how expensive, how soft the inside is, or how tight they seem to fit there is still constant friction between the body and the underside of the bra when ever the car is moving.
Even the very finest piece of dirt that gets trapped between the body and the bra becomes a microscopic piece of sand paper.
I once purchased a very expensive bra for my then new 1979 280 ZX. It seemed to fit perfectly. The instructions said to keep it from getting wet.
The very first trip I took with it on my car I wound up getting stuck in heavy Philadelphia rush hour traffic while coming home from a weekend at the shore. Out of no where the sky opened up and we had a down pour, and I couldn't get off the road for about 20 minutes.
Getting drenched, I removed the bra and proceeded on my way.
Upon closer inspection (after washing my Z the next day) I could plainly see the outline of the bra "wet" sanded into the clear coat of my hood and fenders. Never used one again.
This was just my personal experience 35 years ago, yours may vary.
