I’ll be teaching you how to make some grungy metal with a star in this tutorial.
First create a new document then fill the background with an appropriate color.
My document size was 435 x 223 pixels and the background color I used is #dbc699.
So after you’ve got your basic background color, reset your colors to black/white by pressing D.
Now go and apply Filter > Render > Clouds, before doing anything else go to Edit > Fade and use about 65% with the mode Soft Light.
Lastly for this step apply Filter > Noise > Add Noise with an amount of about 1.0 – 2.5, I just used 1.0.
Now what you need to do is go and download some realistic grunge brushes. You can get some from PhotoshopBrushes.com.

Create a new layer then brush some nice grunge brushes over the canvas a bit like mine:
Lower the opacity for your grunge brushing layer to about 40%.
