I have a can of Plasti-kote "vinyl color" product number 408 charcoal gray. It's not a perfect match, but damn close. This can is at least 15 years old, I use it mostly for 1/2din stereo adapters to make them a little more attractive than just leaving them black. It may be a "dye", but it has stayed stuck in my 93 Ty for almost 10 years. Other applications are in vehicles I've sold and don't have long term results for.
