Application 08/909,869
temperature, said work to be painted including steel sheets
having various cooling rates, at least one of said cooling
rates being faster and another of said cooling rates being
slower, comprising the steps of:
using a first temperature above the crosslinking and
curing temperature for preheating the work to be painted to
second temperatures above the softening point temperature;
applying the powdery paint to the work upon cooling of
the work so that a one of said steel sheets having the slower
cooling rate cools below the softening point temperature
during this applying step;
melting said powdery paint by heat at a third temperature
above the softening point temperature, and below the
crosslinking and curing temperature to form a film on the work
in a fusing oven before the work is cooled to ambient
temperature; and
coating the work with an electrodeposited film.
