teflon spray, waterproof grease
 

I'm looking at getting some of this stuff for regular maintenance. Do I need
to get this from the LBS or can I get the same stuff cheaper at the
hardware store? What brands do people use? While we're at it what
type/brand of chain oil is the best to use?

Yes, you guessed it. I've clocked up enough Ks to be interested in doing my
own maintenance.

TIA,
Brad
