Vallejo Xpress is another entry into the colour glaze "speed-paint" style of mini paints.
I noticed them on the rack when I went in to my FLGS for some normal Vallejo paint, and thought I'd give them a try in my constant search for hobby materials that cater to my laziness.
They work decently well, though there's nothing startling about them. They dry to a glossier finish than Army Painter Speedpaints, but otherwise seem pretty similar.
The part-painted hag in between the two bottles is FDM printed at 75mm size, and not very well printed at that. FDM isn't well suited to colour glazing, as its layer lines are quite apparent. Plus, my printer is a bit out of whack, and I'm getting a fair amount of stringing and blobbing.
Speed-paint glazes, of any manufacturer, are fine if all you want is a quick and okay paint-job, but they're really not a one-and-done solution. If you want a really decent paint job, they're still just a starting point. They work best on models with plenty of well-incised surface detail. However, they're useful for what they are.
They're a bit tricky to mix reliably, but not impossible. I assume they'd need the appropriate glaze medium for extending if you want to lower the intensity of the base colour; I haven't experimented with plain water, but I think it would tend to interfere with the paint's pooling and self-levelling qualities.
The skulls on the bottle caps are FDM printed from a file I got on Thingiverse; they provide me with a good visual indication of what's going to come straight out of the bottle. They're just stuck in place with a blob of blu-tak in a socket underneath.
