I didn't actually put brush to model, but I spent some time checking out what others did and getting opinions on the paints from my betters. I am a firm believer in the engineering rule, why invent something when you can look it up, so for me the verdict is out and I'll wait until what I hear from the experts. I did have some impressions.
The biggest change is it looks like you won't need to thin down your paint much at all. The paint flows much better, and the new washes, what they call shades, seem to flow into cracks and not pool as much as the old washes did. The base line is much more extensive as well.
The dry stuff, was interesting. I have moved away from drybrushing, so I don't know how much use I will get out of it, but it may really help those that use it significantly in their painting. This stuff has the consistency of a paste, almost like spackle.
