Awesome! The glow! Remember that there is a search feature. I highly recommend it. In my opinion, it is *the bomb*. While you are waiting for others to reply, you can do a search of this thread or forum for Obenauf's Oil and it will bring up a list of posts where it is mentioned.
I just recently posted somewhere that Obenauf's is messy so make sure you spread out lots of newspaper, are not in a rush and have cloths or paper towels handy. I apply it using the dabber on the lid after it had stopped dripping. I start in the middle of and area and go out to the edges. That way it doesn't pool in the piping lol because it is so runny. It is beyond runny! The first time I used it on a convertible clutch, I applied so much on the corner where a seam is that it saturated through the seam to the interior of the bag! Hot mess. I wish I had video taped myself. It would make a great Do Not Do It This Way tutorial. After I apply it I wait a minute, then wipe off the excess. I have found after using on a tabac/taupe bag the application seemed uneven at first , possibly due to the hot mess application method, but over weeks, it leveled out.
Overkill or not to use Obenauf's ? My disclaimer is that I like to use it and feel it really helps to restore leather that's been used or abused. I find the bags I used it on smell like leather again. IMO it seemed like your bag had a rough ride so I am inclined to think no, it was not overkill. I would suggest over the next few weeks to periodically, if not daily, buff your bag with a soft cloth. That and using it (in all seriousness) will help to distribute and even out the Obenauf's as well as absorb any excess, if any.
And for what it's worth, great bag! Congrats, you rehabber you lol
