Thanks So I start with a grey primer and then an even coat of a light tan. Then start drybrushing every woody colour you have. A bit of silver drybrushed every so often in certain areas. You should end up with a varied colour across every plank. Then start picking out certain planks with slightly heavier or lighter drybrushing. Overall a heavy wash of black wiped across the planks to sit in the gaps. Then another black wash lightly wiped along the planks once the previous is dry. I think I ended up doing 3 or 4 washes by the end. Then brush with dark powders to take the sheen off. Ive done powders on both wet and dry surfaces before, so you can try a bit of both and see how that ends up. If you wanted a replacement plank, youd then have to repaint those the lighter colour with a lighter drybrushing. Its a long process but Ive used similar in both 4mm and G3.
