Silicon sealants exude acetic acid, causing rust and that's why a butyl
compound is used for auto glass installations.

There are a large number of silicone adhesive formulations that do not exude
acetic acid. They are known as neutral cure or oxime cure. Check the
Dow-Corning site for examples.

I've used neutral cure silicone adhesives for decades on satellite
hardware. Some is air cure, some is 2 part.
