Greetings,
I thought I'd share how I paint my gaunts/gants, as I made some pics during I painted my last 3 termagants. As I mentioned before, I wanted to get the huge amounts of gaunts painted as quick as possible but thereby not compromising the quality of the paintjob too much.
So here's how I do it:
1.) Assembly of the model, cleaning of mold lines, obviously. After that I glue on some stones or rubble onto the base and cover it completely with PVA glue. Afterwards I prime with ArmyPainter's "skeleton bone" primer. But you can use a white primer and paint the whole model with bleached bone. But by using bone primer I spare one step.
As a sidenote on primers from ArmyPainter: you have to shake them really well (I mean several minutes!), heat it up a bit by holding it into hot water. And after priming hold the can upside down and spray until no colour comes out to clean the nozzle. I didn't do that with my first cans and the nozzles always got clogged with dried colour before the can was half-empty.
2.) I paint the carapace with knarloc green and the base with khemri brown (foundation colour)
4.) Afterwards I wash the whole model (not the base) with a lightly thinned mix of devlan mud and water (about 3 parts devlan mud and 1 part water)
5.) Usually I leave that to dry over night, but I think an hour should be enough as well. Then I paint the edges of the carapace with terracotta with uneven brush strokes.
6.) The last step is to glue some static grass onto the base and give the carapace an even coat with 'ardcoat for a glossy finish. Some thinned white on the teeth and the magazine of the weapon give some additional highlights.
That's it. Quick and not too dirty.
