The concern here, folks, is if it turns green (i.e., causing oxidation
of the brass?), will it also have the same affect on center pins?

Or was there some other agent involved, such as another material having
been in the same bottle previously? If no one else has experienced this,
then maybe we can write this off as a quirk. If others have found it,
then maybe further investigation is warranted.

I am going to put some Protec in a small plastic bottle with some center
pins today, date the bottle, and put it on the shelf. Maybe in a year or
so it will tell me something.
