A few ~random thoughts follow:
I can't tell if it's cc failure or not. I gather there's no color transfer onto the pad.
Never, ever use Griot's MPs on a warm/hot surface.
Never switch to #3 until it's basically perfect and never apply the wax until you're finished polishing.
If it looked OK in the garage you need better lighting in there
FWIW I sure wouldn't expect Griot's MP#2 to be enough for that job! I can't help but wonder if the product was over-worked :think:
If that was a Griot's orange pad that came apart something's weird as those pads usually last forever.
I'd do as
Eliot Ness suggested, but I'd probably do two passes with the DC#1 and then multiple passes with the MP#2 (unless you have some MP#1 handy). If it' cc failure it needs painted anyhow, so I wouldn't worry too much about being too aggressive..as if you could *be* aggressive with MP#2

The only time it ever acted remotely aggressive for me was on single stage..when used by Cyclo (whole 'nother situation compared to PC/Griot's orange pad...and I liked it by Cyclo a lot better).
