Dyeing lambskin Tom Ford boots from light brown to black?

I'm debating purchasing these Tom Ford ankle boots, with the intention of dyeing them from light brown (Factory original color) to black. I always wanted the black ones but don't have the option to purchase as they've been discontinued...can this be done safely and without damaging the leather? The boots are a very soft lambskin and my only concern would be a hardening of the leather/significant change in texture. Additionally, can I protect the gold hardware from darkening? Pictures attached, I would love to use your products for this/whatever you suggest, thank you!

>>> dyeing them from light brown (Factory original color) to black.
We have to bare in mind that to block off the base color we need an “opaque” system rather than a “transparent” system converting from “aniline” to “pigmented” finishes


>>> The boots are a very soft lambskin and my only concern would be a hardening of the leather/significant change in texture.
With added coating to block off the base color it will have a slight increase of texture micron thickness or double the original finishes thickness. Will also have an extra load to the overall leather structure. However, leather suppleness depends on the fat and oil moisture level of the leather structure and can be improve with replenishing it to about 15% to ensure no stiffness to the leather.

>>> . . . can this be done safely and without damaging the leather?
Any solvent or degreaser used and when absorbed by the leather will dry up the “fat and oil” content and stiff up the leather that will lead to cracks when not replenished with Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system prior to color refinishing it.


>>> Additionally, can I protect the gold hardware from darkening?
You may tape it off with those green masking tape used in painting.

Therefor you will need this Leather Doctor Kit-Sa7.cl and we can modify the instruction to suite your project accordingly to achieve your desired result.

Leather Doctor® Kit Sa7.cl, micro-pigmented leather color refinishing kit is design for a holistic restoration approach to not only the finishes but also rejuvenating the leather for suppleness. Most of these repairs may range from missing finishes to abrading damages into the leather structure. Some expose areas may be contaminated with foreign soiling that includes conditioners, protectors, body oil, grease and sweat or alkaline overexposure from cleaners. A comprehensive repair for a long-term lasting solution will require a holistic approach to deal with both the exposed structure and surface finishes. The practical and functional softness and strength of the leather depends on the health of the structure with average thickness between 0.9 to 1.2mm from stiffness and cracking. The aesthetic aspect of the leather finishes averages 0.02mm (or 20 micron) in thickness for practical compressing and flexing from cracking. A leather-safe restoration system begins by stripping with Stripper-2.3 and rinsing with Rinse-3.0. Degreasing with Degreaser-2.2 follows with Acidifier-2.0. The suffix numbers of these four products denotes it pH value for recharging the protein fiber ionic positive besides the act of decontamination. The leather integrity is revitalizes once the ionic attraction between the positive protein fiber and its negative leather constituents like the tanning agent and fatliquor (fat, oil and water) is initiated. Leather rejuvenating system for softness and strength is accomplishes with Hydrator-3.3 follows with Fatliquor-5.0. Surface uneven absorption is seals with Adhesor-73 to reduce the need for color over-coating thus increase its flexibility and stretchability from premature cracking. Protector-B imparts a non-stick rub-resistant surface with a buttery feel, reduces noises that translate into less friction wear. As the leather surface is well lubricated it reduces compression when comes to heavy body contact thus reduces compressed creases and wrinkles.

Instruction:

Stripping Existing Deteriorating Finishes:
1. Cover and tape off frames, trims and protect flooring.
2. Mist sprays Stripper-2.3, Eraser-4 scrub with help of 2000-grit sandpaper feathering out seamlessly and towel extract for an even appearance.

Degreasing:
1. Shake Degreaser-2.2 to gel prior to use with a repeat shake and rest until it gels.
2. Transfer to Eraser-4; agitate to saturate the stain, feather out to the entire section.
3. Towel extracts suspended soiling after 10 to 30 minutes or before it dries until it shows clean.
4. Spray Acidifier-2.0, towel extract until it shows clean to a healthy squeak.

Hydrating:
1. Spray Hydrator-3.3 saturating the stain area and feather out for an even appearance.
2. Covering with tissue paper without airspace to trap wick up stains instead of remaining on the leather surface as it dries.
3. Peel tissue paper when crispy dry and use Eraser-4 to erase surface residue prior to fat and oil replenishing.

Fat and Oil Replenishing:
1. Spray Hydrator-3.3 to precondition the leather prior to fat and oil replenishing.
2. Spray Fatliquor-5.0 and redistribute with foam brush until saturation.
3. Repeat application each time water contents evaporate until fully saturated.
4. Drive remaining surface remnants free of milky fat and oil until it turns clear with Hydrator-3.3.
5. Allow natural drying for extra softness.

Dry Prep:
1. Erase wick-up residue with Eraser-4 prior to repairs.

Adhesion Promotion Coating:
1. Apply Adhesor-73 by foam brush to seal surface uneven absorption rate and promote adhesion simultaneously.

Color Coating:
1. Apply color matching Micro-54 + 10% Thickener-48 for flow control and airbrushing for professional result.
2. Fine dry atomize dispersion with more air is achieve with 80 to 100psi of air pressure.
3. Light spray is preferred and let dry in between coats to build up color coat.

Top Coating:
1. Shake the product well and apply by airbrushing for professional result.
2. Use lint free paper towel to even out drips and streaks.
3. Speed dries between coats with help of hair dryer.
4. 2000-grit sanding may applies to improve touch and appearance.

Rub-Resistant Protection:
1. Mist sprays Protector-B redistribute with a foam brush / paper towel and ready for use when dry.

It will be easier to dye a lighter color such as light brown to black rather than black to light brown. Choosing high quality product will minimize the texture and quality change in this boots.
