is that metropol blue?
that might make dying a bit tricky. But that's what you need to mask the cracks.
Leatherique would definitely help although that product is meant for non-coated leather that you would see on 20 year or older cars. The boxster and 911 seats are coated but i still does a good job of cleaning. But for routine cleaning I prefer to use 1Z leather with a terry towel.
