ok, an update for anyone else who's thinking of painting their frame.
4 newspapers, 3 rolls of masking tape and 2 cans of paint and its done. I used plastikote super enamel paint, matt black. rubbed the original paint down with 800 grit, degreased etc then 4 coats of paint. Masking up took about 3 hours and was pretty boring, but i wanted to make sure it was all sealed up. I didnt think around the yokes would work due to everything in the way but it come out great.
