First off, I tell you from expensive and painful experience that these vehicles have lots of "edges" where the pain is thinner; plenty of opportunities to burn it with a rotary. Use extreme caution around door jams and hood corners.
If it were me, and it's not, this is what I would do:
1. Wash/dry.
2. Clay with great care...take your time.
3. Start with SSR2.5 with an orange pad and see how it goes.
4. If that doesn't work try SSR2.5 with a yellow pad.
5. If that doesn't work start the process over with SSR3.
6. SSR1 with a green pad.
7. Glaze.
8. Finish up with whatever wax or sealant you prefer.
