Baby Oil will soak in and soften up hardened plastic, but it won't restore the color.
When we redid my wife's Pathfinder, I used baby oil and then after it had soaked in for a few days I used a dye. Some of the pieces I replaced, rather than try to fix. It is 24 years old, after all.
Rick at ADS recommended a product called Showroom New. The product comes in both grey and black.
Took a few coats (I'd suggest 3), but it ended up looking quite nice. It can be put on with an applicator, or for larger areas, a roller.
It even stuck on faded hard plastic, like the plastic parts of the grill that had completely faded. The texture disappeared as the product dried.
I think it's more like a paint than a dye. But, it's been on the car for 5 months, and still looks good.
Don't know why AutoGeek doesn't carry it. I thought it worked quite well.
Make sure you put on some gloves, or you'll spend some time getting it off your hands.
