A while back while building a suit for David (DHB) I made a quick tutorial on how I layered the colors on a P1.
"Ok guys so I just finished the front of the torso and I just wanted to explain a bit the process I do :
I start with a base sand color, then I lower the PSI in my compressor to create a splatter pattern (or you can use a 1 inch brush or tooth brush and use the finger flickering technique). I use magenta, burnt umber, and deep blue with that technique. Also i do some veining with a "0" and "1" brush ( I used to use the airbrush but i notice that i have better control with the brushes.) For veining I use a purple gray and reds.
I use a burnt amber and burnt sienna and try to draw small noodle patterns all over the skin. Also I start making some of the first black spots, Try not to fall into one same shape for the spots, try to make it as natural as possible and use different shapes. (BE PATIENT) this part takes a LOT of time.
Do some spots using browns, that will break a bit the black spots and make the skin look a bit more natural. Paint all the armor with a black base. Using a reference picture, spray sepia or a dark brown where the brown undertones as shown in the reference picture.
Using a sponge apply silver but take excess off with a paper towel, once all armor is done I make a mix of alclad mirror aluminum and deep blue and using a brush hit some of the corners and parts where armor got damaged. Do the same with just the pure alclad but focus more on the damage and add scratches with it. Dry brush some gold ink on some flat (undamaged) parts of the armor NOT TOO MUCH.
Finally spray a bit of black over the armor to give it a dirt look to it. (on parts like backpack, cannon, gauntlets I add a bit of light burnt umber to give a more mechanical look) Bring colors together with a light coat umber over all the skin.
Seal your work with Liquitex varnish hi gloss ( I know some of you would say that why would you use gloss on a metallic part like armor and no a matte finish??, but I have a couple suits under my sleeve and with rubber inks I notice that hi gloss last longer than matte, so there is your answer lol)
I use a 1 inch brush to apply the varnish and i do 2 coats."
I hope this help you a bit.
