I gave the Duplicolor clear a week to dry - today I sanded it with 1000, 1500, 2000, and 2500 grit.
I then used Meguiars Ultimate compound, Scatch X 2.0, Meguiars Cleaner Wax, Polish, and then some Carnuba wax.
I finally attached the caps to the mirrors with some 3M double sided tape - here are the results:
Overall - I am pretty happy with the results, I wish I could have buffed it with my DA Porter Cable - but I really couldn't put much pressure on the caps not being attached to the truck. I'll probably buff in a few months with the PC, and use my much better quality Adam's Polishes and Sealants next time. The color match is spot on with the rest of the truck and look way better then the crappy black plastic that was there before on the old mirrors.
I forgot to post about puddle mirror from the Escalade mirrors - plugged right in and gained an extra light at night:
