Hi Pete, My RN medical was even more damning! After much toing and froing with coloured lenses and some contraption called a Martin Lantern (pinpricks of light) my red/green perception meant there were very few options left to me, not a pleasant experience and my RN service was short and not particularly sweet. In practice it's never been an issue in the ensuing 44 years! Regarding EDSG, I shall probably just use what I've got in the paint stash and see how it sprays through the airbrush. Whilst rattle cans are a great time saver, my spray booth is small and the garage alternative is not welcoming at this time of year.
