Sealant / Adhesive....... Permanently

FWIW, my favorite method of joining two wires is the Harbor Freight crimp connectors with the shrink tubing lined with hot glue around them. When you shrink them the hot glue melts and seals the shrink tubing to the wire.
They come in 3 colors/sizes (small = blue, medium = red, large = yellow).
Very inexpensive, and when installed with a good crimping tool they are permanent, water tight, corrosion resistant, neat & clean.
Give 'em a try.

8200 is kinda like 3M's 5200 works great and is permanent but very messy.
The joke is "It's so messy, if you order some over the phone it will get in your hair."

Similar to Prussian Blue. Buy small tube. Take home. Open cap, but do not use. 2 hours later it's on the toilet seat, your glasses, the cat and inside the cookie tin. Amazing.
