Back on the building of the Clone Wars Y-Wing, that was on pause for few monthes.

A black preshading is applied all over the paneling.

Rather than use a pure white, I went for an off-white mixture of tamiya XF-1 Mat White with few drops of tamiya xf-19 Sky Gray, and few drops of Klir/Future. The mixture is highly thinned and then airbrushed at very low pressure. This takes a little more time because you have to apply many thin layers, but you have total control on the result.

Left: still one or two thin coats. Right, it's done. For each one, the nozzle end remains to be done because I was holding them there (by the way, it allows to visualize the technique).

Here, the white is done.

Engines and turret guns are covered with steel, then silver only on the nozzles. Machine guns will instead receive a silver drybrush
