I used a water based brown to paint the ply (fence panel stain) and then, once dry, I used silver and black tester pots from B&Q .
I just twisted the brush in a circular motion in alternative colours, let it dry and did it again.
To get the rust effect, I used a water based varnish and painted the edges before sprinkling cinnamon power on to the wet varnish.
Load of drawing pins around the edge, I had to drill every hole as the pins would not push into the ply.
I might try a little bit of green paint around the pinheads......
