I just talked to my friend about the car insurance today. She just changed the windscreen of the car and the amount she insured is not enough to cover all. She still need to pay some for the tinted. I also changed the windscreen before. However, for my case, it is not costs that much, I no need to pay any extra. For this windscreen protection, you will need to inform the insurance company when you bought your car, if you want to get insured. If not, it is not including inside the policy. Most of the insurance companies is the same. If you are not sure, do read the car insurance reviews and make a comparison before you decide on which company to sign up.
