Repairing a "pig" radio housing

Step 2: The challenge

In the 1st photo you can see that this radio housing had hundreds of chips and cracks in it.  The crack highlighted in the 1st photo went all the way to the bottom edge, then across the bottom (2nd photo) to a large missing chunk of housing (3rd photo).  There were many other cracks as well, such as the long crack in the 4th photo.  Obviously this radio had been dropped at some point in time.
