My girlfriend has a white Cherokee she purchased a year or so ago. She got a good deal on it because it had slight discolorations on the driver's side quarter panels. The carfax showed a slight fender bender (some sort of parking lot accident if I remember correctly). I've attached pics below. The discolorations aren't uniform and I can't feel them when I run my hand over them.

Anyway, we just started looking at removing them tonight and I'm hoping someone on this forum can give us some tips on possible removal techniques. I've tried alcohol and a magic eraser but neither helped - a google search mentions a clay bar?

Thanks!
