none of the tutorials I went to mentioned anything about this only working on vinegar tanned oil.

Here's what the leather on the coat looks like.

Sorry to say it is not going to work on that finished leather. Again you can try it on a small out of the way area to prove me wrong The other thing it will not change the color of the stitching it is not a dye. It works on Vegtable tanned leather. It is not going to work on chrome tanned. Chrome tanning uses chromium salts in the tanning process. Veg tanning uses the tannins derived from thinks such as oak bark vegtable roots etc. The tannins are infused in the leather during the tanning process. The reaction of the tannins with the viegroon is part of the chemical process that causes the blackening. With out the tannins the blackening is not going to happen. Even if it was veg tanned leather the finish would not allow the vinegaroon to penetrate properly and if you got any colorationat all it would be splochy. Since it looks like it has already been dyed a light gray even on veg tanned leather the vinegaroon would not change the color again it is a chemical reaction not a dye.

"Vinegaroon, or vinegar black, is a natural method of coloring leather using iron and vinegar that dates back to ancient Rome. The vinegar solution reacts with the natural tannins found in vegetable-tanned leather, creating a beautiful dark slate gray. As vinegaroon is not a dye process, the color never fades or rubs off. Its permanence was preferred by leather workers throughout the world for centuries until modern dye methods were introduced over the last 150 years."
