No worries, that seems fairly straightforward overall in that the abutting hinge surfaces could go unvarnished but sanded, (I'd use dot stickers, if you don't feel like fiddling w/ hand-cut tape pieces) followed by a light dusting of graphite (ie. shave some pencil lead into a creased post-it and then sift it onto them [and into the rod's channel, for inc. smooth action]). The rest can be clear coated to your preference. (leave said masking on until this step is complete & dry cured, fyi [24+ hrs])

FWIW, gloss first and then matte for super durability as IIRC, the gloss particulate is torus-shaped whereas the matte is spheroid, and this method nests them neatly for a better bond. It's how I've sealed my TTRPG pieces for decades, and while possibly anecdotal, the results are night & day in my experience. 🤘🏼

Oh, and if it needs mentioning: do not construct it fully and then varnish the whole model in one piece. That will glue the thing shut. 🫡
