Hmmm the 'Great Experiment' is pretty much over with using Masking Fluid through a needle tip. I find that it is just too uncontrollable to give fine detail results (especially on these small models). I'll save such for eye sockets and cockpit glass when airbrushing. Below are the steps I did tonight on 5 of fifteen flesh-hounds. I was very happy right up to the last step, removing the masking. Looks like it will be fine haired brushes for these burning areas from now on. It won't take much to fix them with the airbrush, so it was a worthy experiment...

Base orange and yellow in horizontal gradiants

 Ghost-tint orange shader to make oranges brighter before masking.

Adding the masking.....

Deep Purple base-coat

Dark Blue in pronounced areas

 Airbrushed blue-grey over major muscles

 Gore red to give a mauve/heated metal look

 Getting the mouth ready for future colors

 He's...all there....

 White socks undercoat (will make yellows pop when sprayed over)

 Medium yellow sprayed over white

 Brighter red sprayed over yellow

 Orange sprayed over red and yellow

 Mask removed....not pelased but then liquid is hard to get to dry where you need it...
