Pipe dope on my temperature sending unit. Is this okay?

I remember seeing some writeup or video or something a while back where someone experimented with putting various amounts of teflon tap on a temp sender to see if it would affect the reading. I think he did everything from no tape to something stupid like 10+ turns where you'd barely even be able to start the threads. They all showed the same resistance, so I probably wouldn't worry about it and have always done a couple turns myself as cheap insurance.
