This should not take too long (24 hours?) as you will be making more of a tinted thinner rather than thin paint. You should also add some Winsor & Newton Liquin to as a flow aid. Don't forget to clear coat the model first as this will also help flow. (I'm not sure about the drying time because working the next day has never been a problem for me.)

I have been weathering with acrylic washes but do not like the effects of the surface tension in the water based media. I have started to try and use artist oil paints from a tube. My question is what is the drying time for this method. How many days should one let the model sit before handling it or adding more effects?
