you'd be amazed how far they go to reduce weight, friend of mine found this out the hard way when he was asked to buff a Lambo, but they tend to only use 1 layer of paint. He wipped it right of the car.
Makes sense when your trying to save ever gram, think how heavy a gallon of paint is? :thumbup1:
heard somewhere talking about how they saved more weight by making the glass in the windows extra thin to save a few grams ...
