That diorama sounds good Chris, shame it's gone to the Great Display Cabinet in the Sky!
I think Wayne does it both ways, and you can do some on the gloss coat, but quite often, depending on what you are using, it might not 'stick' to the gloss. I normally do the main stuff on the matt paint (if I've used matt paint, as I sometimes use gloss paint first, then do a matt coat.), then apply the clear gloss, then, if possible, and if required, do some more weathering etc, then the matt coat. If it is still needed, or I want a 'fresh' look to, for example, paint chips, then this is done last, whilst doing any retouching etc.
