Roger,
This client has 2 Alligator leather chairs. I think they are real and not just embossed. We are hoping to just clean, Hydrate, and Fatliquor to even out the color and nourish them. It feels and looks like suede next to scales. Let us know how we should proceed and if you think they might need some dye and how we should approach that?

Roger,
There must be a glitch with your forum, I could only download 1 picture at time. Usually I can hold the Ctrl key and grab multiple pictures at the same time.

Fading may be improved with Hydrator-3.3. The saturation has to be high with a longer dwell up to 72hours. The hydrating moisture content has to be kept high (moisture easily ooze out when finger pressed) throughout the hydrating process. This process will help to disperse tanning coloring or dyestuff to the surface evenly. Any blotchiness will need the help of Acidifier-2.0 to even out its pH value. Surfactant-3.6 will also ease out any surface tension.

These nubuck effect is the result of removing the surface layer of skin and should be treated as nubuck using the Leather Doctor Nubuck Care system:

If we need to add some color back, I guess we would Aniline-21?

Aniline-21 is the base structural dyestuff originally used for aniline, semi-aniline, suede and nubuck - it is a staining dyestuff that works by “hydrogen bonding” (a “positive” ionic leather protein fiber that link with the “negative” ionic dyestuff) on contamination free structure and surface. When the leather structure is contaminated with body oil, grease and sweat, as an example the result may be blotchy. Surfactant-3.6 is first applied to observe any surface tension that may result in blotchiness prior to Aniline-21 application, to save the tedious task of removing otherwise any dyestuff unevenness.

That is why Aniline-76 is developed for aniline surface coating.
And Nubuck-17, Nubuck-28 and Nubuck 29 developed for Nubuck.

Note this chair is a combination of Aniline and Nubuck finishes and should be kept distinctly separated to retain its original characteristic appearances.
