"Outdoor Paint Effects"
from Abe Books
Are you talking about installed window frames? Clean the window frames with hot soapy water, mask off what you don't want painted, clean again with a rag and alcohol (denatured not 90 proof) and use a spray paint that has MEK / methyl ethyl ketone as one of it's ingredients. The MEK will soften the powdercoat and help with adhesion.
