If they could, they would still use old school paints and powdercoats. Far cheaper, and dosent require near as expensive of equipment to apply it.
Unfortunately the EPA and other overseas gubbermint bureaus that regulate factory emissions dosent allow for it.
Instead of solvent based they use waterborne that is electrostatic bonded and baked or a plant ester based dry coat.
Lot better for the environment but way too thin and not very durable at all.
