I used water based Minwax stain, it was about $5 at the hardware store.
I used Testors Ivory paint over primer .
I did a bunch and let them dry , then a second dip
after the second dip the stain has set up nice in the low spots, seems that it works much better on the second dip and has a more even coat.
here is the same figure after I added some thinned down bleached bone to add some highlights and cover some of the stain that was on the high spots that was unwanted.
Some say that you should basecoat eveything first, but I didn't want brown shadows on the rest of the colors on the model so I painted the other colors , washed them with a black wash and highlighted.
