One model I have is the Forgeworld Ork Kannon. I am intending to use it either with my Squiggoth or other Ork vehicles.
The model goes together really easily.
One of the key things you need to do with virtually all Forge World models is to give them a good wash.
When the Forge World models are cast, the mould is given a spray (I guess) of some kind of lubricant to allow the cast model to be released from the mould easily. However the lubricant also acts as a barrier to paint, so as happened with previous models I (and others) have painted is that the paint flecks off.
Washing the model in water with a drop of washing up liquid should remove the lubricant. Avoid using hot water as this could warp the resin (a useful tip if you need to warped resin back to its original shape).
Once washed the model is then ready for painting. The model was given a black undercoat.
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.
I did realise only later that I had in fact bought and used Nuln Oil Gloss Shade rather than the Nuln Oil Shade. So as a result I gave the Kannon a drybrush of Leadbelcher to reduce the shine.
This is how the model compares to the KillKannon which I am using a white undercoat and a basecoat of Leadbelcher.
I used some Agrax Earthshade to add some colour to the weapon, to show weathering as well as wear and tear.
