Hi dvdmks,
I'm currently working on a new paint range that mimics the
GW color range almost 99%, I'm just getting thoughts on it so far and may well send out some trials if there is enough intrest.
I'm looking at supplying in 20ml and 50ml sizes, coverage and shades are almost near perfect replicas.
I've put a link to the thread.
Alternative Paint Range equal to Citadel Colours - Thoughts
But in regards to your question, I have been experimenting with brands such as liquitex and that includes oil paints, painting pens, entry level acrylics, poster paints, sharpies etc and nothing ever seems to come close, there either isn't enough coverage, too many layers are required or the cost of the paint makes it prohibitive. My potential line works in the same way as the
GW line coverage wise and dries quickly too.
