The warrenty should cover the product.. the tint not where its installed... if the product is bad it should be covered. Even if its illegal, should be covered especially if you signed a "Off-road use only" disclamer... if you didnt sign one... they can get in trouble if you get pulled over for it.

Mn law 50% that is it... no tint on front window at all.

The company I went thru in Minneapolis,Mn... LIFETIME warrenty... werd!
