Or if you are cheap like me......
......mask of the vertical glazing bars first, as this is easier than masking each panel individually, and then paint, starting with the interior colour first, before applying the outer colour.
Once all the verticals are complete, do the horizontals, and so on.
it is time consuming, but with a little patience produces a very neat canopy.
This isn't my idea, I got it from 'Eagles Wings', by Nicholas Wigman.
