1. Create a new document.
First of all create a new document, use any regular banner size (I’ve used 530×140)
Download this 3D render and open it in Photoshop, now copy it into the new document.
2. Duplicate the render
With the Single Column Marquee Tool 
do some pixel-streching to the render.
Duplicate the main render, apply Filter > Brush Strokes > Spatter with any old settings, set the layer mode to Lighten and erase a few parts with a soft brush.
Duplicate the render again, move it up to the right a bit and set the layer mode to Darken
Pixel stretch a part of the document again to the right
To bring out the detail a bit apply Filter > Sharpen > Sharpen
This is what it would look like if you applied Spatter to the pixel stretched layer and stretched it again
3. More details
Duplicate the render layer again and set the layer mode to Lighten
Stretch a part again and maybe use the Dodge tool to lighten up a part or two
Create a Curves Layer ( Layer > New Adjustment Layer > Curves… )
This is what I made from that particular part:
