I can't speak for Larry, but since you posted to the list...

I wouldn't use anything as flammable as kerosine.  Drills often 
produce sparks.  Any thin oil like CRC Cutting Oil should work fine, 
and is much safer to use.  Flash rust is a non-issue with aluminum, 
and a lubricant that contains water will help keep the bit cool. 
Thats what I use.   Imho, plain silicone and multipurpose sprays 
(like WD-40) are too "soft" and evaporate too quickly.  Not that it's 
an issue with Stooge panels, but the use of silicone lubricants also 
requires extra prep if you are going to paint the metal later.
