Most amazing product EVER!
Love this stuff so so much, It's a life saver! I originally got it to use as a rubber like coating for a horse hair whip I was making I needed something to clean up the area where I glued the hair to the whip. This stuff worked beautifully for it. Then I started using it to seal up cracked water buckets from the winter 😱 and now I use it for anything and everything seriously wish there was an option to buy it in a giant tin lmao I want to try to seal the bottom of my bfs boat with this stuff bc I can totally see it working wonders!!! -Dries quick -Isn't too stinky, a little bit but not any worse than other glue or paint products -Multiple coats work best (2-3 ideally) -Covers thick holes/cracks well -Doesn't drip or run -Can seal its lid shut a bit so advise putting a tiny bit of Vaseline along the rim for easy opening

Ideal waterproofing coating for electrical cables
This product was used to seal a repair to an underground electrical to a telephone cable. It was easy to apply (3 coats, 1 day apart) and, so far, no problems after 2 months. Being bright red it was easy to see what parts had been treated.

Very effective for outdoor antenna work, and for color coding cables.
Always on hand in my ham shack and laboratory for the purposes in the title. Brushes on quickly and smoothly, dries to handle in a relatively short time, and completely weather ready overnight. No failures here in any Texas weather from desert heat to panhandle snow and ice to hurricanes at the coast. HIGHLY RECOMMENDED.

Works well
I'd heard of this in a few places and decided to try it with my latest project. I purchased both the Black and the Red for 12V applications. It is fairly odorous so use in a ventilated area. I applied liquid relatively thickly so that it was opaque and it takes a little while to dry. It dried to a fairly flexible coating to stranded copper wire, adheres to silicone, cable nicks, other wire insulation and solder joints well. So far the compound has remained in place and has not torn or begun to peel in a couple weeks. I cannot attest to being a water proof coating, how it would stand up in abrasive locations or longevity so use with common sense.
