The following steps should achieve:
We've basically finished the armour, flesh and fatigues, so let's do the final touches to finish our Guardsman! I think these bits are just as important as the rest of the model - no matter how well you've painted his armour, flesh etc., if you've neglected the details it really shows. When I first started painting I'd do most of the model but not be all that happy with it, but once I started finishing off the details it really pulled the paint job together and looked much better! So let's pick up where we left off:
24. We'll start with the chin strap - paint the lower parts it with Bleached Bone. (No picture).
25. Wash this with Devlan Mud.
26. On to the belt accessories. Paint the grenades and canteen with Gnarloc Green.
27. Wash the grenades with Badab Black, and the canteen with a heavy wash of Devlan Mud.
28. Once dry, highlight the raised areas of the grenades with Gnarloc Green, and do a 'rough' highlight of Gnarloc Green around the canteen. I say rough because I don't want it to look to clean and pristine - it gets used a lot!
29. Paint the handle of the knife with Graveyard Earth.
30. Wash the knife handle with with Devlan Mud.
31. Highlight handle with Graveyard Earth.
32. Highlight handle again with Snakebite Leather.
33. To make the leather of the belt accessories look worn, drybrush some Codex Grey over the surfaces which would see a lot of wear-and-tear, such as around the edges, the studs on the pouch and canteen, and the tip of the bayonet holder (is it still called a scabbard if it holds a bayonet?).
34. Going back to the chips on the armour, underline some of the more prominent ones with a thin line of Dheneb Stone. I tried white, but it didn't look quite right.
35. Overline them with a Scorched Brown. This simulates a 3D effect on the chips.
36. Paint the base with Scorched Brown. Make sure this covers the black properly, (especially around the rim) so this may take more than 1 layer.
37. Now we've done most things except for the weathering pigments and metallic colour. We need to do the spray varnish now (otherwise it will kill the metallics) so grab your model and give it a spray. Make sure you wait for it to dry before you continue! It's wise to test the spray first on an unimportant model (or a bit of sprue) to check that you're not going to destroy your hard work!
38. If you want 'wet' looking mud, paint some satin varnish on the base.
39. Now we need to tie the Guardsman into the base. He's trudging through thick mud, and it looks a bit odd without some consequence of that represented on the model. I use Vallejo's Burnt Umber pigment, mixed with brush-on Vallejo Matte Varnish (to get it to stick to the model) and brush that on around the boots. I try not to go too thick, so you can still see the colours underneath showing through, but just do what looks good to you. The matte varnish works very well - once the pigment mixture has dried, even scrubbing at it with a toothbrush won't take it off easily.
40. Drybrush the mud with Calthan Brown and then Graveyard Earth to give some depth and variation.
41. If the areas where the metallics will be painted have stray coloured paint on them, it's a good idea to paint them black now. There's not enough pigment in the metallics to completely cover the area easily, and you may find underlying colours tend to show through.
42. Paint all the metal areas (knife blade, if applicable, aquila, lasgun nozzle, grenade pins etc.) with Gunmetal.
43. Wash these areas with Badab Black.
44. Highlight with Gunmetal.
45. For some select spots, highlight with Chainmail. This is rather bright, however, so don't overdo it. (The Chainmail highlights here are much too stark - I since went back and dulled them down with thin layers of Gunmetal).
46. To protect the metallic paint, it is a good idea to paint some satin varnish on the bits that will get handled lots (such as the bayonet blade) to stop it wearing off.
And we're done! Hopefully you'll have something looking like this:
So in only 46 easy steps, we have our Guardsman! Now I realise that's a lot, but most of these took less than a minute to do. In addition, you can omit some of the layering (such as on the flesh) if you want to cut down on the amount of painting. I think all the work is worth it though, especially when you see a group of them together.
Even if you've only skimmed this guide and haven't painted up a model yourself, I hope you might have picked up an idea or two. In any case, thanks for reading, and happy painting!
