I bought some of this Lahmian Medium the other day, and got round to using it recently on my Maulerfiend.
Its interesting stuff, and described to me as the actual 'base' of Citadel paints.
The new Citadel range can be thinned with water easily enough, but that actually has a very different effect on it than this stuff. This made it far nicer to work with when I added a few drops 50/50 with the Gehenna's gold that I always seem to have trouble with. It made it smooth and a pleasure to work with. 2 coats of my mix gave a far better finish then 2 coats of Gehenna's with water.
I was also told that its basically a matt varnish. And is the opposite number to the 'Ardcoat clear gloss they also do. I think these 2 are hidden gems in the paint set. (I often use Ardcoat over the painted lenses of eyes, lights etc to make them reflective like glass.) The matt Lhamian can also be used to put Decals on, and this is great, as it 'glues' them down better, and seals them on, far superior to water, and gives the decal the same reflective qualities as the paint underneath and around it, making it look like the decal is painted on, rather than plastic stuck on.
I'll still use water for a lot of work, or larger areas, but for medium to small details, this stuff just made the paint 'feel' so much nicer.
Very happy to have found this stuff, and I think its something I'll use a fair bit, like 'Ardcoat, liquid green stuff, and Nuln Oil wash :-)
