Greetings.
Am after a compound that does not dissolve in water, gelatinish, that can be penetrated by a needle to touch a solder blob/pad under it and recharge a lithium cell and when the needle is retrieved, leave no path for ingress of corrosive fluids.
Is to recharge a lithium cell. When done and needles pulled, leave no conductive path exposed for electrolysis as the contraption will be submerged.
What product would you use ?
Trying to avoid wireless charging...

There are some self-healing plastics out there that you could consider using

EDIT: also, you may consider using SUGRU

 

Thanks; did not know about that Sugru product. It does not harden?
What are those clear conformal coatings seen in some moisture proofing printed circuit boards ?

 

My first reaction is to use dielectric grease like Super Lube.
