Iwatalube, necessary or not?

I use it but only on the plunger under the trigger. The pin thats fastened to the trigger goes through a rubber washer before making contact with the air valve pin. This rubber can sometimes be a bit sticky causing a slow return or sticking trigger

Likewise, I never thought of using it on the needle, though.

I use some Ann Summers stuff my wife has when I run out of my regular stuff...but I won't rabbit on about that.
