It's called Swissvax Leather Healer.
This product is specially mixed to match the exact color of the factory leather at the swissvax factory. Each bottle takes 3-4 weeks to receive from Switzerland.
We applied it to the Coral red Boston leather found in this BMW 135i we recently detailed.

Here's how the seat looked before:
First we cleaned the surface to be treated and grinded the frayed leather using the grinding pad. then applied the Leather Healer. We ended up applying about 5 coats with about 30 min between each coat.
And the finished result!
Thanks for looking!
