The Nissan Path

Hi Everyone. I got my '08 Pathfinder's rear bumper scratched up in a parking lot. The lease is ending soon so I don't wanna be charged an awful lot for it.

It's a fairly superficial scratch. I was hoping someone could recommend something that can conceal it, just so that I don't get screwed when the lease ends. It doesn't have to be perfect. The bumper is some sort of plastic/polymer, definitely non-metal. Does anyone happen to know of what I can get at a car store that works well to conceal these sorts of scrapes? I was thinking something analagous to rubbing compound, only that's compatible with the Pathfinder's bumper surface; I just can't afford a body shop right now.

I took a couple pics of it:

Thanks in advance for your advice.

You just need to make sure it's warm and dry enough to do.
