BAT - For Metals dry giving them washes with Blue inks, Purple inks.
Brown, Chestnut and Green inks for a dirtyier look. You can then shine the areas, you want up later.
Dulcote is the king of all Varnish. I spray my mini\'s with satin Varnish first then, once dry Spray the Dulcote over the top, to take all the sheen off. When using Dullcote, shake it extremely well to stir up all the Matting Agent, if you don\'t if can leave a white residue on the mini.
P.S. The finished mini looks great.
