Thanks a lot and Hats off to everyone over here for providing help and guidance to everyone and specially to the beginners just like me, who asks very lame questions, but experts guide them in a very good manner. Hats Off again.
After seeing everyone's effort over here, i got motivation to detail my white Vitz, i read whole thread and finally decide to dedicate this sunday on my car.So, i visited Saca Plus lahore shop and really enjoyed seeing all the Turtle and Meguiar products in real. Although, i got very much confused what to buy or what not, while keeping in my budget. So i asked for help from the owner of shop, he recommended me 'Turtle CAR WASH', 'ICE SYTHETIC SPRAY DETAILER' , 'ICE INTERIOR PROTECTANT', 'PLATINUM PASTE WAX' and some Micro-fiber towel,drying cloth,wind screen cloth and pad, and finally a Total bill of '5k'. 
Anyhow, i started the work with full motivation and after 5 hours of effort ended with disappointment, i didn't understand when, where and how to use 'ICE SYTHETIC SPRAY DETAILER', please guide me ? Applied it on exterior plastic under vipers , but it doesn't showed any change, still white dryness is there 
Secondly, didn't find any thing from these products for engine bay 
thirdly, washed the car twice with Car Wash n Wax, using two bucket methods and after that applied the 'PLATINUM PASTE WAX' on it. The car was clean, but didn't get the result i was expecting, the skin was not smooth 
Please guide me experts, i have white vitz 2006 model.
