Indeed, but I don't know too much about those. The ones I use (I sound like one of their salesmen at times

) have the advantage of being dead easy to fire through my airbrush and even easier to clean out afterwards. I have learned that the
GW Chaos black aerosol has a lot of blue in it, hence the nice purple colour. I also have a plan to try some of the Alclad II paint sets on my next force, and I am now probably going to skip
GK in favour of getting my
TK stuff done. I will be using a similar green effect on my Sphinx bodies.
I also have plans to re-do my nids just to get the colours a bit more interesting as the Red-Purple/Green effect doesn't give enough of a contrast. I have some candy red to try in the near future as well.
