[RE-wrenches] Acid containment

[Ray Walters]

We have used the underlayment material to line battery boxes.  Turns out 
it gets eaten by the acid too, not recommended.  Really the best product 
I've ever used is just the heavy plastic sheeting to line the inside of 
the box.  I had  batteries crack and leak acid almost 2 inches deep, and 
the plastic sheeting held it.
We try to use large plastic tool/ cargo boxes.  The auto parts single 
boxes are not a good idea for more than a single battery: exposed cables 
and jumpers.
