grease advice needed

[C Fernandez]

Hey Guys,

This afternoon I'm cleaning up a Sony GDM-1602 monitor.  I have the case 
disassembled, and have washed all but the largest pieces.  The base is a 
very nice rotating and tilting design.  The rotation taken place because 
the plastic tilting assembly rides on a flat sheet metal base.  The 
contact area is a circular plastic ridge that was lubed with an 
clear-ish amber grease.

What kind of grease should I use to re-lube this?  I want to provide 
adequate lubrication between the plastic and steel, but I don't want 
something that will hurt the plastic.  I was thinking about using 
dielectric grease, since it shouldn't harm plastic, won't melt out, and 
isn't too messy.  However, it's designed as a moisture barrier, not 
really as a lubricant, I believe.  Thoughts anyone?

Thanks,
