Tips and Techniques by Leslie Eaton

Shake Well

These weathering colours are comprised of many different pigments, some heavier than others. The pigments may separate into layers in the bottle while sitting so be sure to shake the bottle well before using and periodically while using. You may want to use a soft paintbrush to stir the paint from the sides and bottom of the bottle.

Experiment

These colours are designed to be intermixed to create intermediate hues allowing you to have colours that are unique to the item you are weathering. Adding Opaque White or Light Dust can make lighter shades. Adding Transparent Smoke or even Fertile Soil can achieve darker shades. Enjoy experimenting and playing with mixing the colours.

Layers

Apply your weathering using numerous light layers of colour. This will allow you to achieve a greater depth of colour and help you to avoid applying too much weathering. Applying layers of different colours also allows you to achieve the most realistic appearance to your models.
