It was necessary to apply primer and grey paint on two Skin Stiffeners which will be visible in the cockpit (or maybe not after the trim has been installed) - wish someone could advise what parts need painting.
While I was at it, I painted the underside of the Instrument Shelf....just in case someone looked underneath and said "you forgot to paint this bit". Subsequent inspection showed that the paint was a bit sparse in places, but it's not worth redoing something that is unlikely to be seen. I'll probably still lose a couple of nights sleep over it ;-)
