12V Battery Area

The 12V battery is supposed to reside right behind the passenger side rear turn signal.  This area has been shielded with a wood base.  When I first cracked it open it was a big mess.  I'm guessing battery acid had leaked at one point and the water from the oversized tire in the back also leaked through. 

Plenty of room for a battery, especially the 60AH lithium that I use.

I'm not sure if it was all fiberglassed in originally for protection but now comes the fun part - scrapping the crud off to see.  My plan is to spray with truck bed spray so it will protect the area from any further damage.  The ultimate solution would be to replace the old wood and glass it in.  I'll go with a temporary solution for now.
