This is true. But apparently they only have the code to do lacquer and the smallest amount you can buy is a quart at about $100.. Considering a few ounces in a spray bomb will easily cover a dash, that's a lot of extra paint and expense.
There is a guy in Ottawa, Canada selling all the suede colors in spray bombs. He claims he can ship by mail "ground". The stuff is good but I had a real problem getting a consistent finish on the large top surface of the dash (maybe it was too hot out !). Worth an email ...
