Dallas the decals were from K4 Decals, k4decales.com. I don't know if the decal film was softer than others but I couldn't move them as much with the tip of a fine paint brush as I had other decals in the past and under magnification I feel color saturation could have been a little better but the fit the bill for what I wanted to do with this engine.
Mel I was thinking more for texture than finish so I've never given thought too a dirty black or grimy black paint that may enhance the "voids" in the cast load.
