Awhile back, (not sure if it was on this forum) someone was asking about a source for a specific brand of 'polish' to really make plastic parts black.

There were a good handful of replies and someone who uses this stuff showed his engine bay and it looked terrific.

If this sounds familiar, could you give me the name of it - and if difficult to find, good sources?

I'm also open to suggestions for a good wax that really works well on the XF's paint.
