Rust Spots On Paint

[Pitch Black]

Hey everyone!!
2 weeks ago I stumbled upon a deal on a white Alfa Romeo Giulia that I couldn't walk away from. The car is a 2019 used as a demo and never titled until I came along. I have never owned a white car before but have owned a black car for years now. I see they are different beasts! So, I'm learning. As you can imagine, being that the car was a demo it received little TLC. I'm gonna change that! I noticed that it has small rust spots on the rear bumper in the paint. I'm guessing this is the result of the brake dust being aloud to sit on the paint surface too long. I have never dealt with this sort of thing before. Any recommendations on how to remove the rust spots? I was thinking of buffing the car, which it needs anyhow. If I go this direction do I need to toss my pads afterwards?

Clay or IronX, very common and easily fixed. I’m getting the car sat on the lot for awhile? The whole car may need decontamination

I had wondered about claying it. Which approach is more effective? If I choose to go with IronX is there a manufacturer you would recommend?

Yes, I can tell the car needs some "beautification".
