Yup, it did cover tinted depend what premium u purchase and how much u pay for ....... I used to do that when there is some scratch on my tinted( not my glass, hello Vcool not cheap leh) ....

Yes it does effect ur NCB if ur car is claim for Accident but with premium purchase, it won't effect NCB at all ....

Basically u can insure ur car windscreen, accessory and bla, as long you willing to pay .....
