Picture #2 looks like the structure is overstretch that widens up the finish micro cracks that becomes visible. The lower seam missing finish is cause by friction rubs. Picture tells us that this is a pigmented leather finish with a possible satin luster.
These missing finishes are also where the soiling from the surrounding finishes has been accumulated; that may need.
Picture #3 shows deep creases; the result of diminishing fatliquor that leads to stiffening of the leather structure; except to the weakening collapsing or crushing fault lines due to constant flexing; resulting in cracking off the finishes (color and top coat)
How do I fix the defects?
There are too many options to fix the defect, one is short-term fix; the other is long-term fix for at least lasting over a 5 years period. I will discuss how best to have a holistic fix to be worth the effort, you may want to take some of the option out and short-cut it. Just like the three little pigs that build their house attitude.
This is the general structure for a holistic long-term fix.
1] Preparatory cleaning – this is where all foreign contamination is stripped with this Prep-7.7 > Cleaner-3.8 > Rinse-3.0 leather-safe system.
2] Removal of deteriorated finishes – all deteriorated finishes is also removed at this wet stage in conjunction with above 1]; taking advantage of the fact that the leather structure is stronger and the finishes is weaker; avoiding the need to use solvent products for stripping them off; with a combinations of removal tools like – Razor-60 > Wet sanding with 800/1500 grit; to avoid building the new color coating on a weak foundation.
3] Leather rejuvenation – with Hydrator-3.3 > Fatliquor-5.0 is highly recommended to soften the leather up with suppleness and strength.
4] The repairs is done to the overstretch leather structure with Impregnator-26 to seal and strengthen them with even absorbency for the Adhesor-73 and the color coat.
5] Color coating is refinished with Pigment Micro-54 system with Thickener-48 as the flow controller; and the Whites may be shade with a few percentage of Black and hue with Ochre to match you original off-white – see the color range.
6] Topcoat is with matching Micro Topcoat-72S (satin).
7] Non-stick rub-resistant protector that matches the leather type is Leather Scent-B.
