Silicone adhesives are generally a good choice for sealing against liquids, even if the silicone rubber is fully immersed in the liquid and kept there for a long time. But there are exceptions, substances that cause the silicone rubber to swell or break down. Such chemicals include organic solvents and fuels, and - in fact - straight silicone oils.
To seal against these materials, I recommend FRV1106 - a one-component fluorosilicone. It hardens into a flexible rubber with the help of humidity and works like a normal silicone adhesive and sealing material. The difference is that it can be used to seal against petrol, diesel, alcohols, acetone, etc. It can also seal silicone oil, which otherwise creeps into a silicone rubber. FRV1106 is red, decomposes acetic acid and glues well to most metallic surfaces and several plastics. It can, of course, also be used for CIPG with the help of suitable dosing equipment.

The downside? None, if price is no object. Fluorosilicones are quite expensive. But if you want a seal against the above-mentioned substances, nothing else works.
