There is always a scar left from the broken glass, even after the trapped air has been removed. However, the vast majority of repairs turn out looking much better than when left un-repaired. Occasionally, a repair doesn't turn out as appealingly as others because of factors such as the amount of original damage, how old the chip was, previously accumulated dust, etc. Remember that the main purpose of the repair is to restore the integrity of the windshield and your safety, not cosmetic reasons.
