Best way to re-dye in black a Plymouth lower dash pad

I'm searching for the best way to re-dye the lower dash pad for my 68 Plymouth GTX.

I've used Herb's interior paint with good results

I sprayed my dash pad with SEM Color Coat. Followed all the directions to prep it properly, and it seems to be holding up fairly well. There is one ding in it that was my fault when I re-installled the dash, other than that, I'm happy with it.

I got some good stuff years ago to do the counsel in my 68 GTX from Speedy Auto glass. course it was black and they had that in a Vinyl
paint. It's everywhere? Everyone makes it!
