fter attending a weathering workshop by Arry Dodd at the NMRA British Region convention in Aberdeen last

year I was eager to try some weathering using salt to simulate rust.

Not currently having access to an air-brush I used commercially available flat spray paint and my trusted method of using Pan Pastels which in my opinion produces a very subtle suggestion of wear and weathering.

The following photos show the pro-gression through the steps to achieve an overall effect. I started with a 1/43 die cast and plastic Russian car which I found on Ebay by a seller in Moscow which appeared to be the right era for what I am modelling.

This is the first time that I had tried this method of rust weathering and I have since used Tamiya flat spray paints where the final colour is anything but grey. I also used Army Painter flat spray to fix the Pan Pastels and dull the final colour

down, you could also use Testors Dull Coat. This is an easy project to try and the whole process was completed in a a few hours, allowing time for paint to dry before scrubbing the surface with a toothbrush to remove the salt.

There is an amazing amount of detail on this car including the interior which will not be seen in the finished application but as I reassembled the car I realised that the interior needs to be included to keep the body in place.

This process and can be applied to freight cars, locomotives and anywhere that rust and weathering is needed.
