(CleanBright) Liquid Ebony

I know this stuff is old school but if any of you know where I can find a bottle of this stuff it would be awesome. I have a quart bottle with about 8oz left; I don't use it very often but when a cat slides across my car and uses its claws to try to stop, this stuff "Liquid Ebony" gets the scratches right out.
The last I heard "ClearBright" went out of business so I doubt I'll be able to find it. If some of you remember this stuff and you know of a replacement product that would help too.
Thanks all,
