You will need Minwax Tudor (from Ace Hardware), waxpaper, primer, a shallow box, disposable brush, surgical gloves, and mineral spirits.
Step One:
Clean the figure of flash and fill in all the gaps with greenstuff. Base on a stick, a piece of cardboard, etc.
Step Two:
Prime the figure. I use this primer from Michaels/A.C. Moore. Use Gray – it's cheap and cheerful.
Step Three:
Paint a diluted mix of black paint and water over the figures. 3:2 works best: three-parts paint and two-parts water.
Step Four:
Paint the helmet, Bronze; the flesh, Flesh; the mail, Silver; etc. If you make a mistake, no worries, the dip will fix all your problems.
Step Five:
Get waxpaper and put in a shallow box (I use a beer box). Make sure you have surgical gloves.
Step Six:
Mix two-parts Minwax with one-part mineral spirits – Use Minwax Tudor (from Ace Hardware).
Cover the figure with the Minwax/mineral-spirit mix.
Step Eight:
Put the figure, standing up straight, in the beer box.
Step Nine:
Finally, let set for one day in a well-ventilated place. (It smells.)
