There is a chirping noise coming from my ac should I replace the belt? on 2000 Chrysler LHS

Someone looked at the belt and said it was glazed, should I replace it or put belt dressing on it?

Replace it with a GOOD brand (OEM is best in my opinion) belt. Belt dressing just makes a mess (and it tastes nasty).
