Does anyone know what this is?

any sort of machine cut dowel or spool would work as long as the end is solid or close to it. of course it would have to be solid/hard for the purposes shown in the video, as you want to block down the high line of paint, not wrap around it in any way. and i say machine cut because the end has to be perfectly flat and true. trace dowel/spool on back of appropriate sandpaper and cut out with shears then attach to end of dowel/spool with CA or whatever adhesive you want.

someone let me know if i missed something.
 
No I think you're right about that. I think it's a hard, rigid surface. I thought about just cutting off a piece of dowel on the table saw. But keeping creases out of any sandpaper I'd wrap around it seems to be impossible. This (whatever "this" is), seems to be a solution to that. If 3M or one of the mfr's made 1" or smaller round PSA discs that might work, but...
 
I'm curious what other solutions folks have come up with for knocking down the high paint line during deep scratch repair?:)

As builthatch said, you cut a disc out and glue it on.

Um...the solvent (langka) method? Or a regular sanding block? I've used the edge of this one: Meguiars Sanding Pad, wet-sanding pad, Meguiars sandpaper pad

Or you could try one of these, which are very expensive: Meguiars Unigrit Sanding Blocks
 
There are pneumatic sander (circular) backing plates as small as an inch I think. Here's some 2000 grit, 1.5" diameter paper:
Astro Pneumatic 2000 Grit Sanding Disc - 1.5" diam. (or 38mm) (100/pack) - 2000P

If you search a bit, you might find a 1" or 1.5" backing plate and a smaller quantity of small discs to buy. I think you could just hold the backing plate by the stem to manually sand. You could also buy sandpaper sheets and cut the circles yourself (if not psa, get some 3M spray adhesive (I forget the product number)).

There are all imaginable shapes, sizes, and contours of sanding blocks available as well. Try searching a woodworking store.

If sanding a curved surface, I would think you'd want a very slight amount of give (padding or flex) in the sanding block, to allow you to control the feathering better.
 
I appreciate all the input. Thank you.

Well, I'm pretty sure that guy in the video was using a spool of (red) thread. However, after you posted that Festool link, I realized Kevin Brown (the Buff Daddy) sells those (different brand).
