Well I worked at my Canadian commander, so here are some shots of McDuff.
I always Dullcoat my paint job, and then start with a wash of thinned acrylics. The dullcoat protects the original paint. If you screw up with weathering, windex will strip it all off rignt down to the dullcoat, and you can start again.
I am going to do a thin wash of grey until I get the paint looking faded and then hit with a wash of black to pop out the details.
