It\'s really a pretty simple paint job.
Halfords Matt Black - rattlecan
GW Boltgun Metal - airbrush, thin coats, highlight centre of panels / dust edges. Quite thin paint - not aiming for very solid coverage here - approx 2:1 water/paint
Add more and more VMC Natural Steel - as above. Also thin paint, getting more towards 3:1
2 Coats of klear. Neat.
Hairspray and crushed dishwasher salt applied.
Mask areas that will be metal - engine fans and exhausts, nose sensors. Many other areas and detials are actually not on the model at this point or will be overpainted again later so don\'t bother masking.
GW codex grey / VMC black grey solid coat applied. Approx 1.5:1 water/paint
Add more and more GW fortress grey / VMC pale grey in thin coats, highlighting centre of panels, dusting edges. Very thin paint! Approx 3:1 water / paint.
Hairspray and crushed dishwasher salt applied again, in roughly the same areas as before. Note there is NO klear coat at this stage - we want to be able to wear through both layers.
GW golden yellow applied over the grey, many very thin coats (roughly 3:1 water / paint) to build up colour and provide highlight.
Pick off salt / clean with a brush and water. A toothbrush is used to distress larger areas. I had to avoid running the model under water as this tended to remove too much hairspray, but your mileage may vary.
Allow to dry thoroughly and seal with 2 coats of klear.
