Sadly, I was not patient and I went ahead before seeing this, with not great results. I tried conditioning it, then, which did seem to help the bag overall and make the new water marks (?) less noticeable.
Not only that, but this bag seems to be a magnet for stuff and it has another spot of something that darkened the leather from today. I don't know if I should give it another full bath, then condition, then spray it with apple guard? Or keep conditioning to even out the color of the leather, then spray with something? Thanks in advance for anybody's thoughts.
Yeah, I would give it another full bath. Then recondition.
