As I mentioned in my last post, I had used a number of products and techniques which were new to me on my Ultramarines Contemptor Dreadnought. Among these were the AK Interactive Streaking Grime and Rust Streak products.
The Streaking products are all enamel based paints, but much more diluted than regular enamels. This means that, once applied, they can be worked further with a brush moistened with white spirit. Using a flat brush and up and down brushing motions, you can quickly and easily create the kinds of weather markings typically seen on vehicle armour plates as a result of rain and rust - as can be seen in the following pictures:
As you can see, this example was produced rather quickly and roughly to demonstrate the products and the technique. On an actual model, with a little more care, the results look more like this:
The main strength of these products is the ability to continue to tweak and alter the effect even after it has dried by going back in with a brush that has been moistened with white spirit. By doing this you can knock the effect back if you have done too much, or make streaks longer etc.
If you are looking to pick some up, in the UK I would recommend Scale Model Shop. As I was running around in trying to get my entry finished in the run up to Games Day, I made a couple of orders for necessary items and they arrived within 2 days of ordering - top service!
