<snip> I don't know what the actual factory process is but I got the
impression
that the old heat lamp "baking" process we associated with lacquer and/or
enamel auto paint jobs has been changed with the advent of clearcoats and
especially when old solvents disappeared and the products became water
based.
 You'd have to ask an auto paint nurd

 Ahem, I object to being called an "auto paint nurd" LOL, but anyway. It
 just so happens I work in an auto assembly plant and specifically with the
 paint department. I asked one of our paint engineers about the "cure time"
 and this is what he told me. The new paints being used, water based color
 and clear coat are applied separately. The base coat is sprayed and sent
 into a "heated flash oven" long enough to make the base coat tacky then
 sprayed with clear coat. After the clear coat is applied the vehicle body
 is baked in an oven with 4-7 different heat zones, with temperatures
 ranging from 250-400 degrees. After the clear coat finish is baked on the
 vehicle is inspected in the finesse area and polished prior to being sent
 to general assembly for completion. After completion the vehicle is again
 inspected and any defects in the finish are repaired prior to leaving the
 factory. Most new vehicles are shipped from the factory with either a
 protective coating or a wrap on them which must be removed as part of the
 dealer prep. When the dealer prep is done the vehicle is usually washed
 and polished. The paint normally requires 48-72 hours to cure and by the
 time the vehicle leave the factory is has been out of the paint shop for
 about a week or more. You can apply waxes and polishes as soon as you get
 your new vehicle home just be careful not to put swirl marks in the
 finish.
