Mine has turned brown also. I have only ever done it with black but I don’t see why I couldn’t with this color as well. I think it is called SEM Flexible Coatings. It is not really a die as most people call it but when I used it on black carpet and several 70 Cutlass consoles it turned out very good. You could not tell it wasn’t original. I just hope they make it in the correct color, or at least close enough to be ok.
