I've not actually worked on any Fords!
Google tells me it's middle-to-softish so an orange pad would probably be a bit harsh.. 105 is also very aggressive. so would probably hologram it.
I'd start off with 105 on a white pad to be honest but as you're asking I'd assume you have limited experience with machine polishing (not an insult btw
) so I'd stick with your mantra of working up low to high abrasiveness.
Which would technically be Black>205 to begin with, but to be honest 105/205 is a bit old (while having it's place) so yeah.
to finish you'd want 205 on a black pad??
