dunno about Ten specifically, but the glaze medium I've got is Vallejo stuff, which I got from maelstrom. It's not the same as retardant, which just makes the paint dry more slowly. And yeah - glaze medium does help with blending and suchlike. I use it when I remember to. That and acrylic medium (again, vallejo) are the 2 additives I use most.
ps -
skull white still is not very good it dries on my brush or goes milky
how exactly is having thin white paint looking "milky" a bad thing?
and does not really stick to the model.
is your model clean? are you airbrushing it on? do you have fingerprints on your mini? is your other paint not on too thickly (if you paint acrylics on too thick they actually form a paint repellent layer.) All of these could be the problem, not the skull white (since nobody else seems to have this issue...)
I do believe that you, my good admiral, are talking what is commonly known as a bunch of hooey.
This sounds like a good idea. Very fiddly I imagine though.
it is a bit of a pain in the bum, but I kinda do it in wee bits, basically as I feel like it or as I use paints and notice they could do with a refreshing.
