Exactly.... Thats what Mr @Sdogar is not calculating. All the other expenses which are incurred in prepping a car to be flawless and ready to be glass coated. Only compound polish is Never sufficient for these coatings.
Let me tell my process:
1)Wash
2)Clay
3)Again Wash (To get rid of the loosen contaminants)
4)Depending of the condition (Either Compound OR Light Cut Polishing) to remove swirls and imperfections
5)Finishing Polish OR Glaze
6)I P A Wipe (To get rid of the polishing oils in the paint for proper bonding of Coating with the painted surface)
7) Glass Coating OR Sealant
Now comes the expense of Labour / Electricity / Rent / Misc Expense / Products / Tool Wear & Tear etc...MOST IMPORTANTLY I would put my Share above these all. Afterall if after providing all these services with top brand products and investing 10 - 12 hours on a single car, If I am not earning anything, why would I be doing this ??? Do u see any point ?..
So, to get good services You have to spend good. Not overly priced! but reasonably priced.
Secondly Bro, Car detailing comes under "Services Industry" You can never compare service charges with others. Some provide low level services and some provide niche services. Both would be on opposite ends if monetarily compared.
The link of Amazon says 64$ for the Cquartz coating. Order it and get it delivered to Pakistan. You,ll see the frieght and custom duty charges for yourself. We are importing Nanolex coatings from Germany and hence i know that the price you see on your screen is way too low from the price you actually pay to get the product in your hands.
