That sucks!
Everyone in CA with car insurance has uninsured coverage. It comes with the policy.
This sh*t would fall under vandalism and would still be subject to your deductible but you might be able to get the insurance company to foot most of the bill.
You might want to file a report with the police. Maybe they caught a guy in your neighborhood doing this to other cars. My guess is they didn't stop at one.
Good luck.
