Darren. I'm afraid the evening went SHOOM! without ordering any paint.
I like to use professional aerosols from Ketts as they have a nice little steerable jet and they are as good as a spray gun. I more often than not get special colours mixed too, so I stick with a good company.
I usually spray a medium coat of primer filler, then a very light rub down, then a top coat, in three or four light applications.
I can't see you having much trouble with Hammerite if that's what you're happy with, as the object is only to colour the visible part of the ring and make it easier to wash the flies off. You'd probably be okay with a priming coat of Hammerite, a light rub over and then a top coat, as above. The rub down is just to smooth the slight grainy finish you get on the bare Tricoya. If you're worried just try it out on the back.
Out of interest which light are you thinking of fitting?
