The Contrast paints work well on the Infantry models but I wasn't too sure about larger kits.

So far, this Dreadnought is the larget model I have used Contrast on. I'm not too happy with it and will have to consider using it with multiple thinner coats.  It's not that much of a problem. I'm not planning on giving my Howling Griffons any of the tanks seeing them as more of a faster strike force using Outriders and Invaders.

The Contrast paints have worked out fine on the Outrider and an Invader I have completed since.
