What is caulk used for?
The primary use for caulk is to seal any small gaps that have formed along an interior-to-exterior wall. Because it starts out as this kind of malleable material, caulking can be used to fill in gaps of different shapes and sizes.
Can You caulk directly over old caulk?
No. In order for caulk to be effective you want to create a clean seal between your mediums. Caulking over an existing caulk would possibly prevent this and look sloppy as hell. Do yourself a favor and strip out the old caulk first. I'd rather you not. Unless it's an emergency. Go ahead and scrape out as much as you can.

Can I use silicone as an insulator?
Liquid silicone rubber consistently maintains its electrical properties, even when subjected to environmental conditions such as temperature fluctuations and moisture. These attributes attest to silicone rubber being a great insulator for high-voltage components, transformers and other electrical equipment.
Is silicone a good insulator for cold?
Furthermore, the coiled structure of silicone molecules, combined with low levels of force between molecules, also provides good resistance to cold temperatures. These aspects of the chemical structure are also responsible for many of the other properties of silicone.
Why is silicone a good insulator?
Electrical performance The number of carbon atoms in the silicone rubber molecule is less than that of organic polymers, so its arc resistance and leakage resistance are very good. In addition, even if burned, insulating silicon is formed, so it has excellent electrical insulation.

Is silicone good for electrical insulation?
The silicone material may have good electrical insulation properties in theory, but it will be very challenging to apply a consistent, uniform, contaminant-free layer of it on the outside of an existing wire, without special equipment. Any contaminants embedded in the insulating layers will reduce the breakdown voltage. Testing the voltage resistance capability of an inconsistent insulating layer will also be difficult, to measure one portion
Can you use silicone as a sealant?
It depends on the voltage you are working with (for a higher voltage you need a thicker insulating layer), it may not seal well at depth if the sealing system is not engineered properly and the grade and type of silicone will also be critical - e.g. are you potting a device, putting o-rings in or just thinking of gooping the stuff on from a tube. There are also specific grades of silicone for working with electronics. If you are thinking of using silicone as a sealant for such a purpose, I would suggest you get in touch with application engineers who have expertise in what is a specialized area. The people at Dow Corning might be your best start.
