Oh yeah, speaking of - Redyed my drivers seat bolster. It was really, really faded and worn. I used Griots and a fingernail brush to clean it - and wiped the dye on with a microfiber pad. Holy crap, super easy, exact match.
Matched the color using this thread - "the exact match for "hellbeige 2" aka "sand" can be found with Color Number 0521 - Light Sand"
