Lubricating the RB-180 Rotating Base

[RichColvin]

My RB-180 is a bit rough to rotate. I tried cleaning it, but that was only a marginal improvement.  I think it needs to be lubricated.  My first guess would be to use white lithium grease, but am wondering what others may be using?

I use WD-40 for mine and it work great. It's easy to apply, easy to clean and it doesn't collect dust as much as grease does.
