I'm planning on purchasing the UDM. I currently have SSR2.5, opti seal, and Natty's blue. i'm going to be working on a dark blue cayenne S. Is it okay to go ahead and hit it with the 2.5 and an orange pad, then white, then folow up with OS and wax? Or should I do 2.5 with orange, then move to something like optimum polish with white and finish there on?
