When i originally swapped my interior, i was missing a few parts, so i substituted some dyed painted parts in their place.
They wore fine, but I could never get the color matched correctly, especially in the sun. Eventually, over time, i ended up removing the dyed parts and replacing them with OEM stuff.
I'm sure if it was 100% dyed, i wouldn't have noticed as much, but since i had a mix and match setup, it did irk me.
Actually...this thread just reminded me i have an OEM black dash....somewhere....
