I was given a pot of LCD Audi light beige by a mate. It worked well on my D4 Silk Beige front seats and armrests covering well with a few light applications. They do a paint and sealer combined as well as restoring cream. Unfortunately the colour on mine is a little more yellow than the original colour so I may attack again with a lighter shade in the spring. It seems tough and flexible enough.
