Hey there welcome to the world of soft Honda clear! I just did my 08 last week,
First '08 Habanero Red Civic Si Sedan check out my process and looks there but I have a garage and here's what I did...
CG Pro Polish with Blue pad
Polish with Menz PO85RD with black pad
Both of those on the UDM. Honestly I got a good amount of correction with the PP. I wouldn't use anything higher than gray quite honestly. From what I've read the other pads won't finish down properly and you'll be in a bigger mess than you were before.
