most insurances cover that free with no deductible.
@Zephard:
Yes, they will cover it, but be careful. Some insurance companies count rock chip repairs as claims and it could hurt you later. We had a couple one year and State Farm took us out of the preferred discount. We had no other claims, but they told us they were still claims, nonetheless. We decided it was better for us to fix rock chips out of pocket and keep our discount.
Do what you need to, but maybe sure to check your policy first or call your agent first, before officially filing the claim. 4951
