A6 heater, A/C controls

[tugger]

Not a major issue, but a niggling thing, the rubberised type coating on the heater controls is coming off badly as you can't help but scratch it with finger nails due to their position, before buying this one I had seen others that had the same problem. Is there a cheap and easy fix for this? It's bugging me because it lets the rest of the interior down.

Many thanks in advance
