Any silicone, "sensor safe" or not, should suffice. The glass sealer marty59 mentioned is much more liquid than RTV if that is a concern. The Permatex website could spell out the differences but any of the Ultra RTVs would do. The black does have the least odor and dries pliable, the blue is about the same, copper is a little softer and grey dries harder than the rest but is the strongest. The ultra rtvs' curing process can't induce corrosion, something that could happen with the regular formulas (hi-temp red, blue..)
