The Auto Finesse Hide Conditioner is based on a lanolin and wax enriched formula, and features two distinctly important functions. Hide Conditioners first function is to condition the hide by reintroducing essential oils, softening it, and restoring its original colour. Its second function is to act as a protective barrier cream. This creates a breathable layer that keeps the leather from drying out, and prevents dye-transfer on light coloured upholstery. Hide Leather Conditioner is suited to all finished, semi-aniline, and aniline (Sometimes also called Nappa, uncoated, or natural.) leather finishes.
