    Default Is RTV silicone conductive or not?

    So, I was going to use this to seal the ends of some strips after cutting them and adding jst connectors. I can't imagine it would be conductive after it cures... Anyone know for sure?
    On the website, they contradict themselves.

    "Automobile
    Suggested Applications: Door frames, electrical connections, vinyl tops, seams and roofs. (Not recommended for engine gasket or electrical connection applications)."
    (I bolded the text)

    So which is it? Should it be used on electrical connections or not?

    Stick an ohm meter in it and see. If it is as a liquid wait until it sets up and test again. Silicon generally isn't conductive.

    Don't know if it is or not but I remember reading in the forums years ago about GE Silicone II being a good one to use.

    Silicone is not conductive, HOWEVER, you shouldn't use it on electrical connections in our hobby if it smells like vinegar. The curing agent can cause corrosion on wiring and circuit boards. Use GE silicone II or similar instead.

    Thanks guys. I found a different one that claims to be "electronic safe" and have ordered that instead.
