Any tips on removing this yellowing from Tar?

OP has already sanded w 1500

I'd still try it.

Based on what logic?

The OP might be too careful using sandpaper and instead just "scratch up" the surface. With compound on a towel you can put more "passion" in the are being worked and actually remove what's needed. Hope that makes sense. I don't think anything would really work well if he had to get 800 grit just to diminish it slightly though.
