I love it when folks with no experience with an idea or process voice strong opinions based on ignorance.
This process works very well, though I've never seen it recommended for use with Elmer's Glue. The preferred is Titebond II wood glue. The process is the same, but it does take a few applications to get the feel of it to get the surface of the vinyl covered smoothly and without runoff. I used Freezer Paper (essentially a wax-type paper) under the record so if glue does come off the record while you're smoothing it out, it doesn't stick to anything.
It can be messy if you're not careful, and you don't have to apply it on a turntable. Once you get enough glue on the disk by applying it with the pointed dispenser, circularly around the record, I just use a plastic credit card to distribute it smoothly on the surface. The glue doesn't stick to the card, either. Just peel it off when dry.
When you do the peeling, start from the edge of the record by lifting the glue layer up and away from the vinyl. Keep the peeling large and move slowly. Avoid leaving little pieces or strips of glue on the vinyl. They're a bear to remove individually. Too thin to pull up the tiny layer afterwards.
I do reserve this step for seriously messed up records. There's no point in going through all of this process on records in good condition that you could clean normally (though it won't hurt anything unless you're sloppy with the glue). I follow this step with a standard two step Disk Doctor cleaning and rinse on an RCM. If the record is still particularly noisy after this much, an application of Last record preservative adds some lubrication that quiets 'rough groove wall' noise down a bit.
