Alright, so a coat of CPR took all that extra dye off wonderfully. However, at the time of the day it was when I was applying CPR, the sun was streaming directly onto my workspace so I was really able to see spots where the dye was not completely overpowering the red. This surprised me. I figured black dye would be a complete blackout. I was getting excellent application coverage and seemingly great saturation everywhere, even in corners, edges and deep seams both inside and outside. I used some small paintbrushes to get under the folded over edges on the stitches and deep into seams. However, the dye didn't seem to penetrate as much in the tight spots and even along the strap edges a little bit. That tells me I didn't or couldn't get those tightest spots prepped, and probably should have done two preppings with alcohol all over concentrating in those tight areas. But I only did one.
On the inside, on the smooth leather down underneath the creed and across the very bottom, the dye didn't penetrate as much as I'd have liked. It did penetrate, but there is still some red that comes through in direct sunlight. Of course the bottom of the inside will never see direct sunlight by anyone except me, and that would only be if there was barely anything in it, so this is the type of thing where I probably should just.... let it go, LET IT GOOOO!! Now that song is out there floating in your head. You're welcome. I applied a 3rd coat of dye, in the direct sunlight, making sure to get those spots that still revealed some red tinge, but it is looking like this coat is doing the same thing the 2nd one did, which is sit on top of the leather. Would it be a disaster to try to dab some alcohol lightly to the areas getting the thinnest saturation, if it is, say, along the outside piping or strap? I don't want to ruin what evenness in saturation I have now by getting neurotic, and its just in the bright sunlight that this is noticeable. I have a slight apprehension that the bag will look exactly the same after the 3rd coat as it did after the 2nd, but I'll see what I end up with this afternoon.
I admit I already miss the red color. Because of that, I am leaving the zip pocket interior red as a reminder of what this bag was born as. I will never be able to sell this bag, not that I ever would, but pretty much never could without disclosing that it has had a novice dye job.
It is possible this bag will always look like a warm black versus Coach's typical neutral or cool black. I'm taking ample photos so I will do a before and after post maybe next weekend after I apply the Resolene to seal, and everything dries and it is usable. Reminding myself it is OK to not be able to control everything to the nth degree.
TLDR; after 2 dye coats and removing excess with CPR, coverage was great but in bright direct sunlight there was a reddish tinge that shined through in some areas. In other types of light, this was not noticeable. This morning I applied a 3rd coat of dye but it seems to be doing the same as before, drying on the top of the leather. Hopefully this afternoon I will see better coverage in the thinnest saturated areas. General anxieties aside, it's going to turn out fine for a first time dye rehab. It was completely unwearable with the black stain, and so this was necessary because this bag only has ONE LIIIFE TO LIIIIVE!! Cue opening music and ample amount of nostalgia to replace that hideous Frozen song.
One thing I’m confused about......I did end up buying this bag, even though it’s technically not vintage.....that might have been stupid of me.....but I liked it and it looked in pretty good condition. And...... I was impatient, mostly 
But the creed does say “full grain leather “. So would that be somewhat similar to what I would have gotten had I waited for a true Vintage bag?? I haven’t received the bag yet to really look at it.
I will see then, when I receive it, whether it needs to be dunked. If I just wanted to wipe it down on the outside, and handles, just for a light cleaning before the CPR, is there a particular product you recommend?
Which now has a couple of Dooney’s! I am not quite sure how that happened.
