phew! no pics yet, my server crashed a couple days ago
All that mess in that last pic cleaned up amazingly well with only M205 on a white, 5.5" pad. After such luck there I picked out a nasty little scratch on the trunk lid, which happened to have one of the water spot etchings next to it.
For this I swapped to 4" pads and started with orange and the M205 because I knew the white would not cut it here. This didn't quite do it either, so I got the M105 out

Such a difference in working with the M105 vs M205, the 105 kept drying out on me... Texas heat (even in the garage) and the work lamps 5 feet away were to blame I think, so I hit the pad with a light spray of water, seemed to help. I also quickly learned with a smaller pad, you need to work a smaller area...
It didn't do much more, so I switched to the M105 on an orange pad. I blended the scratch nicely I think, the water spot etching is still there though, and one tiny piece of it turned white, I'm guessing a little spot of clear coat failure I caused on the edge of the etching...
Much to my amazement, there were no visible scratches/swirls/marring in the paint after the M105 and orange... this Toyota corolla clear must be something!! Still, I finished it up with M105+white, then M205+white, then some ZPC+black.
The ZPC+black left what looks like tiny tiny very faint water spots all over the paint. Even after wiping with some QD, I'm not sure if they will show up in the picture... We'll see.
<heads outside to hit it with some M205+black pad to rid of the tiny faint spotting>
Ok so they are all over the paint - even in spots I didn't do. It does look like the starting of clear coat failure and is *slightly* worse in the area I just worked on.
Got to love learning cars... 99 corolla getting sold/traded soon.
Just put on a layer of Z5 filler, waiting the 15min then wipe off... then some #845 to finish it off.
Then to fix my server so I can post some pics

Took a few shots between each stage.
