>>> What is the solution to the microcracking? Longer hydration?
A longer Hydrator-3.3 dwell will relax the tightening tension, opening up the interfibrillar spaces within the leather structure to allow a free excess of the Fatliquor-5.0 to hydrogen bond with the leather protein fiber giving added strength and suppleness. These microcracking areas need to massage out so that the leather will produce a “fine-break” instead of a “coarse-break” you see as creases. Cracking is broken fiber and it is too late that might use Impregnator-26 to strengthen it physically within the leather structure.
>>> Also I was not able to remove the white stain and blue paint mark with prep. Is a reverse extraction up for a few days needed?
The white stain need to be positively be identified, if it is solvent based stain such as the blue paint mark will need “Stripper-2.3”. It has a pH of 2.3 to reduce dye bleeding, but will still dries the leather of its original fatliquor. After removing it with a leather spatula or a bamboo skewers will need immediate Hydrator-3.3 > Faliquor-5.0 > Hydrator-3.3 system to replenish the fat and oil content. EffectWax-8.6 is also highly recommended to restore its pull-up effect. Further lost or damaged topcoat will need to be restored with AnilineTop-76G.

>>> Dark spot, is that moisture or need degreasing?
Dark spot is first stretch or pull to lighten it, if it is there for a long time, it is not moisture but some oil, grease or sweat content that need to be degreased and pH balance with Degreaser-2.2 > Acidifier-2.0 > Hydrator-3.3 system
