2 Lube Questions

[PackerTL2@aol.com]

1) What are the types of situations where lithium grease would be a better 
choice than a moly?

2) Is the di-electric grease used on electrical connections intended to be a 
an electrical conductor, an electrical insulator or is it's primary function 
something entirely different? What properties make it especially suitable for 
electrical use?

Thanks
