I have accepted, you are not alone now.
At monkee, that cabinet is what I use to display finished 40k stuff in.
Secret Weapon weathering pigments in the UK from http://elementgames.co.uk/
I have the army painter matte spray but I haven't used it yet (I keep reading horror stories about varnish sprays and it's putting me off!) I have a brush on gloss varnish for gems and stuff.
I used Vallejo Liquid Acrylic Matt Varnish. Works via brush or airbrush. Applied thinly in a couple of coats and works wonders. I then use GW 'Ardcoat for gloss bits like gems etc.
I have used it on all my Tau and so far they have survived. For reference I don't have a foam box for them yet so they all get chucked in a battleforce box and slide around. Contrast this with my Riptide WIP which didn't make it to 1 game and back in its own box without losing some paint
