I've just lightly weathered the top of the boiler/roof with a matt grey (for ash) and matt black to give it that "sooty" layer. Also the wheels and motion rods with matt black, matt grey and a light spray of sand enamel. To give it that look that its been into use. And less of the plastic model look.
I'll get a picture up soon.
Whats your pros/cons on using enamels/acrylics compared to Weathering Powders?
My locomotives are going to be in static display for quite some time until I get my own house (instead of renting) to start my own 40/50's British themed layout.
Also is it and idea to lay down a coat of clear then add the soot/dirt detailing when weathering with an airbrush? IE so it gives the plastic more of a shine as if it were painted metal panels, then lay the matt soot/dirt layers on top?
I want to practice on a few older tender drive models I have before I take the plunge and hook into my good LNER collection. Haha
Thanks for your time and input guys.
