What is a wash?

Washes are highly diluted paints used to bring out the detail in your model and enhance the appearance of the base coat.

Most paint manufacturers have a selection of ready made washes designed specifically for this purpose.

Make sure that when you apply the wash remove any excess wash from the model with a clean paint brush.

After all the idea is to create definition and add shadows to all the nooks and crannies.

If the colour you require is not available, you can create your own washes, weather you are using enamel or acrylic paint by adding the relevant paint thinner. I would suggest starting with a 50/50 mix of paint and thinner.

You can adjust the amount of paint and thinner mixture by adding more paint if the appearance looks too thin or more thinner if the appearance looks too thick, according the look you are trying to create.

There is no right or wrong, it comes down to practice, practice, practice.
