As well as the English Wheel already mentioned several times, the profession of "Panel Beater" is quite literal. The panels are beaten into rough shape with various shaped-headed hammers, and then smoothed out with flat tools that resemble spatulas. It makes one hell of a din and takes a long time.

There are some luxury motor car brands that make a point of still using the panel beating (aka panel patting) techniques for their production. It adds months to the production time of highly skilled, and thus very expensive, panel beaters... but that's the price of oppulence.
