Hey guys, after my dad insisted a couple more tries with the cutting compound.
It is no longer visible unless under direct sunlight, I'm hoping I should be able to buff the rest out.
Failing that, I'll give both a wet sand, and a clay bar a try.
I will post pictures soon, when I manage to find my phone.
Thank you all so much for the help, I truly appreciate it.
And I no longer am required to murder my friend and/or his family.
I will still be getting some form of payback though.
