Preshading using Tamiya Acrylics
Recently on my blog entries and also on my layout thread for Juniper Hill a number of folk have asked about a technique I use call preshading which has its origins in military/aircraft modelling. I used to model aircraft so was familiar the process. The idea is that preshading gives a faded effect to the centre of panels whilst the panel lines appear to have collected dirt etc.
Below is a photograph of the Tamiya acrylic paints I've used thinned with car windscreen washer fluid
I've had a LIMA LMS 42ft parcels van that I detailed a while back but it never ran well. I've changed the bogies to MJT compensated ones and used the Bachmann bogie sides. The roof was treated to a coat of Halfords grey plastic primer.
Then I loaded up my airbrush and sprayed Tamiya NATO black around the ribbing, panel lines and vents as per the photo below.
The next stage involved spraying the Tamiya grey over the roof and as you can see the centre of the panels appear faded and the black paint gives some representation of trapped dirt in the pamel lines.
Here's the roof fitted back on the parcels van.
Once all is dry I like to spray a coat of Johnsons Klear over the roof to lift the matt finish of the acrylics. This then leaves a suitable canvas to add washes and further weathering once dry.
Cheers,
Mark
