Diamond sandpaper came up off the top of my head! I thought I'd made it up.
But just for the heck of it I search engined it. Command shift L; sure nuff;
it exists! I think you can buy it at Walmart. I've never seen it. Or I would
have.  I love sandpaper. Not that I've been in a Walmart for 3 years.

I am serous about abrading surfaces to be glued though. You get a surface
which which is like glass and how's the glue supposed to work? It needs
little crevices to grab onto.  Texture. I read this once I'm sure.
And a quick abrasive swipe will get a slick film residue off the surface of
whatever you're gluing as well. While it adds precious texture.

The other thing about gluing is pressure.
But I don't think it much applies to A&B.
But on other stuff pressure can turn cheap acting glue into killer really
good acting glue.

My name is Mark William Rabiner and I glue things. Very seriously.
