I have used it with great success on:
2500pt Skaven army for WHFB, my first use of it - 30 days to paint the army in full!
Imperial Fists Space Marines, with highlights after.
Lord of the Rings Mordor army. Small army.
ACW and Nap British including highlanders, a small test batch of each.
My French Naps, 3 regiments of foot, 3 guns. One regiment of foot was washed instead.
For me, the keys are:
1. Clean bright basecoat
2. Brush on AP, not dip! Make sure to watch for blobs and buildups.
3. Leave sit 12 hours minimum.
4. Use a matte varnish. I happen to enjoy the AP one at the moment.
Hey, I have a Gold Demon from my serious painting days, and I like the stuff. I think it's faster for me, to get a good tabletop result.
But to each their own.
