...It reminds me a product back in the 70’s that the “Ball” company made for records that was a lubricant and a protector. It was not suppose to build up on itself. Ball (yes the jar manufacturers”) was also a aerospace manufacturer.
There is only a little comparison between the work at the Ball Brothers and by this hacker. Robert Pardee, a Ball engineer, was an incredible audiophile and one of the few people to take a scientific look at record treatments and stylus friction, for example:

He developed a solution that used PTFE to "teflon" coat records (=Sound Guard). The active ingredient in RainX, polydimethylsiloxane ("PDMS", a silicone oil), is the same used in another product, Groovelube. Neither goes on my records, but in one case there was a little research done on application to vinyl records. I'm pretty sure this video guy never read any of Pardee's papers, but you never know, he isn't that far off and he brings up the interesting topic of record coatings or "lubricants".
EDIT: The guy mentions the coating "repels moisture". This is true as PDMS, and PTFE for that matter, are hydrophobic coatings (the combination of the two results in "superhydrophobic" coatings in fact). It may seem counterintuitive, but modern research has shown it is more advantageous to
attract water molecules to the record surface while maintaining a hydrophobic lubricant layer (how anti-static surfactants work, as found in products like Gruv Glide developed by Irwin Rowe).
