... if You like the weathering I used... I try mix technique. I paint it with mix between wet and dry brush. I used wide brush with drop of wet paint and do it like dry brush. With this technique you have paint under control, don´t use too much paint and it looks like it is old. Also the paint on the base, blue , white, brown, and copper will be visible, you can control it, You have to start from bottom to top of model, bottom is the darkness, top lighter. As you can see, blue or white part help you to have final effect. It is not very visible on picture only in real model
Some small parts you have to paint with clasic method. See picture
