Lubricant for outdoor lights

Dialectric grease should work but if it cruds up water is getting in from the top, use sicilone caulk to seal the fittings.

High humidity over an extended time will produce corrosion. This from direct personal experience. TB

This is the stuff you want. I used to sometimes break bulbs trying to uncrew them because of the threads adhering. I bought some of this stuff earlier this year after reading a thread about it and haven't had any difficulty getting a bulb out since. BTW: a little goes a looooong way. I bought two little tubs initially but now know one will probably last me for a lifetime.
