>>> It is actually black and the silvery color is just due to the shine off of the light.
If it is due to lost of luster, then it is the topcoat that you will need.
MicroTop-54 comes in four luster level, gloss, satin, matte and dull.
>>> Question: What's the difference between Prep and Degreaser? They seem to be used interchangeably from reading some of the forum?
Both Prep-7.7 or Prep-4.4 and Degreaser-2.2 are all products for restorative cleaning but used depends on leather types and soiling conditions to achieving the same end result – leather free of foreign contamination.
Degreaser-2.2 is obviously design for degreasing both above surface and most of grease are also penetrated that goes below. As it has a pH value of 2.2 both degreasing and controlling bleeding at the same time it used in all leather types.
Prep-7.7 is a preparatory cleaner with a pH value of 7.7, thus only safe on non-absorbent leathers mainly pigmented where the water pools on the surface of the leather. Worn areas is not safe as it goes into the leather structure thus Prep-4.4 is used instead.
Prep-4.4 is also a preparatory cleaner with a pH value of 4.4 and recommended for all absorbent leathers with general soiling.
All the above 3 products is used as a system with other matched products thus:
Degreaser-2.2 > Rinse-3.0 or Acidifier-2.0 for surface soiling and Hydrator-3.3 for below surface soiling.
Prep-7.7 > Clean-3.8 > Rinse-3.0.
Prep-4.4 > Clean-3.8 > Rinse-3.0 or Acidifier-2.0 for bleeding control.
