Context: So I began repainting them all in enamel on larger , custom - built timber frames . Enamel 's qualities have spoiled me , I guess . But then the advertising billboard effect of this series - which , after all , underscores its consumer - critical , super - feminist concept - is lost unless the surface of the individual paintings is as glossy , flawless and glistening as the paint job on a new Ferrari . The trouble is , working with enamel takes a terrible toll on my health , no matter what I do to protect myself . I ' ve had to evolve an almost industrial process which exposes me to its carcinogenic fumes only for brief periods .
