Card cars exist to solve one specific problem: a body shell is full of doubly curved surfaces, and from a flat sheet those can only be made by dividing them into narrow segments. That is why a card car is respected work — a finished model with a smooth wing means the builder can roll and tab properly. The print meanwhile carries paintwork, chrome surrounds and plates, so nothing is sprayed at all. Rolling a compound curve out of flat segments is a skill that transfers straight to plastic bodywork, where the same shapes arrive moulded and the work moves to paint instead: the kits are in car and formula model kits, and printed sheets on every other subject in card model kits.
