How to repair this Urethane Coating Peeling of this Bi-Cast Leather?

I am wondering if you sell a repair kit for bi–cast leather. We do not have a rip. The very top layer (urethane layer? It shows a facsimile of leather grain) has been nicked and on the inside corner of a rounded–off arm this layer is coming off very noticeably.

I contacted you earlier this week and you sent me an e-mail with product information. Below, are two photos of the damaged couch with bi–cast leather. After reading your e-mail, I still was not sure which product was correct. Also, I don't need enough to make a quart. Besides the urethane coat peeling off we have a cat whose claws scratch the couch as she jumps on and off. It looks like you sell surface maintenance products. Would something like that help with the cat scratches?

> Curling of Peel:
The curling edges can be bond back by using Leather Bond-3D. Just place the bond underneath and press it down to dry.

> Missing Urethane Coating:
This missing urethane coating can be recreated by using Adhesor-73 as the base for the Aniline Dye-21. The ratio of mix is about Adhesor-73 3part to Aniline Dye-21 7 parts. This is applied by layer to reach to the intensity of color and film coating. Thereafter, this coating is further protected with a soft urethane topcoat to match the luster with Aniline Topcoat-79G (gloss).

> Matching Color:
This is custom color from probably Yellow/Orange/Dark-Brown to match – Test it out on a clear plastic film and place over the area to match.

> cat whose claws scratch the couch as she jumps on and off:
This buttery-feel Protection-B+ will surprise the cat, and quite sure will never want to return to the jumping on and off. I
have observed similar situation, where the owner says that the kitten didn’t jump on the sofa anymore – slip and falls the first time!

So the above is how you would repairs the peeling damage, with products such as:
1] Adhesor-73
2] Aniline Dye-21 with color Yellow/Orange/Dark-Brown custom matching
3] Aniline Topcoat-79G (gloss)
4] Protection-B+ (buttery-feel)

But prior to repairs, the surface is recommended to have a restorative cleaning with this kit.
