shotime, a few suggestions:
I would reverse the order...go SSR2, PP, then SSR1.
Pro Polish will give ultimate clarity, while SSR1 is more of a wet look. Therefore, you would essentailly be canceling out the effects of SSR1. As for the color on your Stang, I would go as wet as you can get it! SSR1 is similar to a glaze (not as wet), and I have started skipping my glazing step on most of my client details, however, I still use it on my own cars. I apply with a PC on a rather fast setting with a Meg's Finishing pad.
Honestly, I would probably skip the UPP step. #7 does have bonding issues, so my suggestion would be to go from 7 to EX, then TS. UPP, being a sealant, MIGHT have bonding issues, but when it comes to all that scientific stuff, none of us really know the truth.
The NEW AND IMPROVED method of removal on #7 works fantastic!! Charles, you should really give it antoher shot.
Trade Secret should be an excellent choice for a finishing touch!!
Good luck, and would love to see some pics when you finish!
