[Vwdiesel] Rabbit droppings # 123 -- ( the back to school geezer )

[William A. Thompson]

Electronically gold is used mostly for high
electrical conductivity,
 low-resistance connections and resistance to
oxidation. I have
never heard of it used for heat reflection
although it is used
electronically for heat conductivity.
I use a pencil eraser to clean gold contacts.
