Anyone used anything that will restore the outer visible part of the be liner to a black instead of grey color?

Use tire shine

Also heard an old wives tale that olive oil works also. Not 100% of the legitimacy of this though.

Just spray it with Sonus trim and motor kote. 303 will work great as well.

When Mine started to go, I oversprayed it with Rustoleum bed liner (in the spray can)

I used the stuff to do my faded cowl, mud flaps and step pads, It works great for those (still dark black after 4 years) so when my bedliner started to fade, I hit it with the spray on liner.
