Well it is nearly finished, just have to do another set of numbers and weather... the later is very important because...
I was feeling lazy and decided to hand paint on the yellow rather than mask and spray. In the end it probably took me longer and more effort, however I wanted to document the process for those modellers without air brushes how to get a good effect.
Here is the (almost) finished article prior to weathering:
When weathered the colour (which is a Citadel "Bad Moon Yellow" paint from Games Workshop) will blend in with the decals and the paint imperfections will go away... well that is the plan!
To get to this stage I first:
Applied a grey undercoat. I should have used a lighter grey. It is good practice to put a grey undercoat under colours like yellow and red to give depth.
This yellow (like many) is quite "thin" so I applied a number of light coats of paint.
Now to do the last few decals and then the fun part, making it look dirty!
