Stage 9:Paint fine details
I confess that I forgot to photo this stage! But it's easy to describe: apply any decals, via your chosen method. Paint small details like glass view ports etc.
Stage 10: Apply chipping
This is a fun and easy stage! I used a sponge to apply small chips across the model. Basically, take a dark(er) colour and dip a small piece of sponge into it. Using tweezers, dab this across your model.
I used Rhinox Brown, and went further by highlighting the chips. Take a lighter colour than your base coat, and a detail brush. Paint the underside of each chip to simulate depth.
This stage can be skipped if you are in a rush!
Stage 11: Apply weathering powder
With weathering powders, it's important to apply them in the appropriate order, and to build up layers. Don't use huge amounts and then be surprised when the model looks unreal. It's better to build them up with various colours, carefully, using multiple fixative coats as well.
I prefer MIG weathering powders. I applied powders to the exhaust vents and other areas that would generate heat. I sealed those areas with a dab of MIG "Pigment Fixer".
Then I went round the model again, applying more weathering powder - mainly to the underside but all areas which would attract dirt. Again, I fixed this.
Stage 12: Seal with varnish
Seal the model again with another thin coat of varnish. This will protect the wash we applied earlier, and also the weathering powders - if you game with your models, these are very prone to coming off if you don't seal them properly.
Here is the finished model...
I inverted the colours on the engines, to add some variety. Note the heavy staining on these parts.
Metallic parts were painted with a dry brush of Necron Compound, followed by a heavy wash of Nuln Oil; this creates a really dark metal.
I will be adding the drones later...
This shot shows the underside. In applying the weathering powders, I did so directionally: simulating the movement of dust and grit as the Devilfish hovers.
That's it for now - a fast and easy way to paint weathered tanks and vehicles!
