When I was a XTC competitor I used One-Shot for years and thousands upon thousands of cases. How many stuck...Zero.
I used to use a small box either cardboard or plastic, small shoe box size, and place probably 40 223 cases in the box. I would spray quickly back and forth covering the cases. I would then let that sit for a minute or so, shake the box back and forth, mixing the cases well. Another pass with the lube, again, let it sit for a couple minutes and then size away.
I stopped using One-Shot when I gave up XTC, and needed more precise sizing for SF prone games. Loading for an AR match rifle, cases were sized enough, probably some a bit more then needed, but they all feed, fired and ejected just fine.
Using One-Shot for precision sizing proved to be a guessing game on how much and how uniform you could lube the cases, as always too much lube regardless of the kind equals too much sizing. All I use now is Imperial Sizing Wax, a bit slower, then everything as we get older is a bit slower.
Guessing game? All I use it on is long range competition brass and no issues sizing it with one shot. Loads very accurate ammo.
It is unreal how thoroughly people over-complicate things. The only One Shot case that I ever stuck, was doing the individual casing spray thing. Just put a bunch of casings in a zip loc, spray in a good spray of One Shot and shake rattle and role thoroughly. Open the bag and let the carrier evaporate for a couple of minutes and there is no problem. I have done thousands of cases this way. If you do not let the carrier evaporate, you will have more issues.

One Shot works great but make sure alcohol all evaporates. Even after a few hours brass is ready for resizing.
And they smell nice tooAfter getting a case stuck with one shot, and looking at the cost, I will never use it again.
I now just dip my fingers into a jar of coconut oil, run the batch of cases through my fingers to coat and then off to the press. Never a stuck case and they size as easy as imperial or any other lube I have tried.
Cheap and effective. Easily wipe clean with a towel.
The only problem I have ever had with One Shot was when sizing Lake City 7.62 cases that were fired in a machine gun.
The cases didn't get stuck but they let you know the brass was fired in a fat larger diameter chamber.
I tested some loads yesterday with One Shot left inside necks after resizing.Don't worry about getting One Shot in the neck. I actually make sure I do get it in the neck and leave it in there. Doesn't hurt anything one bit. I stand the brass up in a loading block, spray them from above at 45 degree angle (without the nozzle that comes with it) on all sides of brass getting it inside the neck as well. Let it sit about 5 minutes after spraying it before sizing it. After sizing it I wipe the outside of the cases off with a rag/towel and it's done. Been using One Shot since I started reloading, no issues.
