Patrick, is this the University report on alternatives to WD-40 you were

keep it.

Left handed drills have the battery polarity reversed as well...requires a 
special charger. :-)  Also don't forget to have a metric crescent wrench 
available to take out the remains of the zerk fitting when it gets loosened 
up.
