>>> Passenger side is torn at seams, is this re-sew-able?
Leather shrinkage is one issue that has cause the sewing thread to give way. It is re-sew-able, and is recommended after the leather is rejuvenated that has return to its pre-shrunk dimension with Hydrator-3.3 > Fatliquor-5.0 Hydrator-3.3 system. Replenishing the leather structure up to 15% of fatliquor (ionic negative charged fat and oil) when dry will increase the leather tensile strength. With a 2000psi leather tensile strength the leather is strong against stitching tear. A strong leather would have a round needle holes and a weak leather shows needle holes as slanted or elongated with eventual split.
>>> Back seat passenger bucket seat has antifreeze stains.
Antifreeze pH value is on the alkaline side of the pH scale. Leather is acidic and has a pH value of 3 to 5. Thus the antifreeze denatures the leather by shifting the leather ionic negative, which repels or break the hydrogen between the ionic negatives constituents like the tanning agent, dyestuff and fatliquor. A low pH system to neutralize helps restore or reverse the leather protein fiber ionic positive with CleanPro-1.5 > Acidifier-2.0 system (the suffix numbers denotes the products pH values).
>>> All seats have wear, and need to be reconditioned.
Fatliquor is an volatile organic compound (VOC) and will diminish through time, accelerated heating or leached (breaking of hydrogen bond) by alkaline solutions (in this case the antifreeze stains denatures the leather). One sign of leather denaturing is the tackiness when damp and stiffness when dry. pH conditioning sets the leather chemistry integrity and fatliquor replenishing or conditioning impart suppleness and strength to the leather. Wear is reduced when the leather rub strength increases with Fatliquor-5.0.
>>> I'm thinking all seats have oil, sweat, water, fading etc. seats REALLY rough condition.
Body oil, grease and sweat issue is rectified with Degreaser-2.2 > Acidifier-2.0 > Hydrator-3.3 > Vachetta-2.8 system.
Water Stain is rectified with CleanPro-1.5 > Acidifier-2.0 > Hydrator-3.3 > Vachetta-2.8 system.
Fading is rectified with Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 > AnilineTop-83G/AnilineTop-76G.
Color refinishing is an option with Micro-84 > Aniline-86 > AnilneTop-83G/AnilineTop-76G > Protector-B/B+
Surface roughness is rectified with Adhesor-73 prior to color refinishing.
>>> I am wanting to understand which kit is required for my issues
See this King Ranch Leather Repair & Refinishing Kit-K8.cl. Product mentioned are found as individual items and refills as individual items are also available accordingly.
