PlastX is good stuff

I picked up a bottle of Meguiar's PlastX today on a few recommendations I've seen here and at Becoka's photography forum. Definitely an improvement over the Brasso I had been using. These pictures are at the resolution of the detector on my camera.

I presume you can get this from a typical auto parts store, right?

60 years into this hobby and I'm still working on my Lincoln set!
The stuff on the slab was an abraision that I was able to polish out, not gunk. There are still some scratches, but they don't impair visibility and they are out of focus.
I polished the slab in a circle for a while, then with linear motions. When I buffed it, it was primarily linear, but I changed directions. I don't see any streaking effects.
