IMO, bras look like ass. Touch up paint makes it a 5-10 foot car, while a bra makes it look bad from 100 feet away. I mean, unless you own a laser red mustang that has lived its entire life in the sun, that’s the only reason you wouldn’t use touch up.
Plus bras are expensive, and you can’t even try them on like the department stores do. If the plan is to paint it next year, just wait till then. You’ll be wasting your money otherwise.
If you’re considering doing this to protect the new paint, there will be rubbing issues, which is why it’s suggested to remove it in a car wash. There’s also UV issues. The previous owner of my car had one of those chrome Christian fish emblems that were popular in the 90s. Took it off like 3 years later, and the image was forever ghosted onto the nice paint. And this wasn’t even metallic flake, which would be worse.
Wanna protect the paint, either go for a full complete vinyl wrap, or just give yourself more following distance on the highway, or even try avoiding it when you can.
