Awesome job.
I love Obenaufs LP. The oil can get rancid...learned the hard way. I used leather therapy on a nubuck duffle and a large flap. You have to apply it very evenly and it takes about a week to dry but the results are amazing. I buffed mine with a dry terry cloth to bring up the nap. (knap?)
Thanks for the tip on Leather Therapy. I accidentally applied it to a small suede patch on a Fossil patchwork bag and it didn't seem to hurt it, in fact it looked all the better for it. I will use it with confidence on Coach nubuc in the future.
