“If it’s on the Internet, it must be true, right?”
This kid is like that grizzly bear guy who eventually got eaten. He’s trying things, and because he hasn’t died yet he makes a YouTube video and tells other people to do it.
CorrosionX is an excellent lubricant for metal parts in use on boats, fishing reels, even some marine batteries. But it doesn’t mean you can immerse an electrical motor not intended for underwater use and not get shocked.
And it’s not a seal, it’s a lubricant. A nonconducting lubricant. Which means:
A) it’s quite likely to warp plastic/nylon parts, which may absorb it unevenly
B) it not uncommonly interferes with an electrical connections in the places where you would want an electrical connection. (Google CorrosionX servo)
So good product when used as intended, not likely to help with the original question.
As for the video…listen to the second guy, who keeps saying, “Don’t try this at home.”
