I have been digging through my workbench models and realised I had a fair few Forge World Ork Weapons. I decided to go ahead and finish them off.
When I made the Kannon which came with the Gunwagon I gave that a dry brush of Boltgun Metal.
I decided that I would paint the Kannon with Leadbelcher, now that Boltgun Metal is no longer available.
I did consider to give the model a white undercoat, but in the end painted the Kannon with Leadbelcher.
This new paint covered quite well and did remind me of Boltgun Metal, so a good replacement.
I then gave the model a wash of Nuln Oil Shade.
This toned down the brightness of the Leadbelcher paint and made the weapon more matte.
I was a little annoyed that the shade wash had gathered on the main barrel.
I think I can sort that out by some remedial work with some more Leadbelcher. I am intending to use other washes and drybrushed to finish the weapon off. I am trying to get an effect that I did with the Ork Bommer engine. Making it look oily and rusty.
