paint sealants are a numbers scam. Here is the math.
Average cost in So Cal = $400 . Cost for the dealership including labor $50.00. Profit = 350.00. If they sell 100 a month, that is $35,000 profit a month.
Most dealerships get 1 - 2 complaints a year. So, as you can see they make out like bandits. Now you know why the Finance guys who sell the "paint sealant programs, window etching programs, alarms, etc. are the highest paid employees at the dealerships.
