I've got three small areas of bubbled paint above the windshield. I'm guessing it is from rock chips that weren't repaired. I soaked them with PB blaster for now to try to stop it from spreading, but I'm wondering if anyone has repaired this before. It doesn't look like it extends down to the windshield seal. I'm wondering if I should try to sand it down by hand and use touch up paint, or if it would be worth letting a body shop take a took at it:
