you have to go to the traffic control department.. pay Qrs. 20 (& guess qrs 5/10 for the stamp) get a new registration card .. then go to anyyyyy car accessories shop (if you want it black) and get the back windows done.. make sure dont cover the front onez or even the rare window... if you want the heat proofing.. then V-Cool, Lamp johnson, Ziabert..Platinum... you name them... (they can give you transparent as well as colored) pricing depends if a 4x4 or sedan...huh ... i guess it enough... (^_*)
