The before and after photos are impressive, but it probably doesn't really work.
Anyone hear of this?

Wow, after reading the Waxidermy thread, I remembered when I bought a few unsealed Bob Marley LPs when I visited Jamaica in the 80s. They has Sterling stamps in the dead wax but were rather thick platters, with primitive labels, one Tuff Gong and the other Rita Marley Records.. I assumed they were pressed locally, as the jackets were crude. Two discs Uprising and Confrontation had strange surfaces, kind of like what was described in the link. They looked baked. They were disappointing sound wise, sounded like they used stampers that were well past their prime, and reground vinyl.

Mechanical scratches are just that. Nothing you can really do.
Several things to ameliorate the issue though (I buy a hell of a lot of older used records, particularly from the 50's and 60's).
1. Use a microridge type stylus. They ride lower in the record groove and since most scratches are in the upper portion of the groove, it can be surprisingly quiet
2. Use a degausser or tape eraser over the LP before every play. Not sure of the mechanism at work, but degaussing a VINYL LP seems to lower the surface noise. You will still hear it, but the amplitude seems to be lowered for some wierd reason and the music will come through more prominently. Doesn't work on plastic LP's: Disneyland, Phil Spector pressed stuff ( really shitty vinyl) , and Bethlehem label ( believe they used some sort of plastic rather than vinyl, at least the early Bethlehems). Don't know of other exceptions but the conventional vinyl LP's seem to respond well. Annnd...degaussers are pretty cheap on Ebay, especially when you look for tape erasers ( NOT tape head erasers)
Of course YMMV
Oh Yeah a friend goes through the bad ticks with a wooden toothpick to smooth out the groove a bit, so that the stylus can at least track through. Takes a bit of practice to get the right "feel" but he's rescued some valuable old stuff this way, or at least made the LP playable.
at least not from back in the day (let's say 50s-60s), they are STYRENE or polystyrene which is much more subject to abrasion than vinyl. it was cheap and dirty.

Yes, I've heard of it and have run into a couple records over the years that I strongly suspected had been "skimmed." It's in effect polishing the lands for a superficially improved appearance. The problem is that the damage in the grooves remains.
You should be able to shave down the lands to some extent without getting down into the part actually played. Of course, if the process isn't very gentle, then I guess you could lose fidelity that way.

Uh . . . No thanks.
