Protek evaporation

[Phil Bondi]

Hi y'all (jimrpt will like that!).

I have put off asking the list about this until I did a little investigating
on my own. I carry a small amout of Protek with me in my tool
case..recently, I have noticed that it is evaporating. I keep it in a
valvespout oiler(Schaff)..and no it is not leaking out of the oiler..it
seems to be evaporating.

I live in a rather humid climate and I keep my tools in my truck overnight.
Has anyone else had this phenomenon happen to them?
