I keep having longer posts discarded due to a security logout. But anyway will point out that not only salt corrodes SS, but fresh water. Dry air exposure creates a protective layer of chromium oxide. That is it's secret and may be compromised by imperfect sealing up. Even the term silicon can be misleading because whether paste or spray the carrier or solvent can be quite different and not do what you want.
Interesting. I had read recently about being careful with spray silicone due to the carrier material possibly causing issues. The recommendation (as I recall) was to spray and let it sit for a while (a few minutes???) so the carrier evaporates.
I have a can of 3M paste lubricant. So I checked the MSDS and it states these chemical ingredients:
POLY(DIMETHYLSILOXANE)
SYNTHETIC AMORPHOUS SILICA, FUMED, CRYSTALLINE FREE
DIMETHYL SILOXANE, REACTION PRODUCT WITH SILICA
Don't see anything petroleum based, which can be bad for rubber. They all have SILO or SILICA in the name. I don't know if any of these are bad for rust prevention.
