Most folks would recommend the 1z series of polishes for ease of use by hand. I cant say for sure how SSR2.5 would be by hand but being a DACP equivalent, then I am assuming that it would require a fair bit of elbow grease! Probably a bit more than most would bother with.
So, my recommendation would be:
1z PP -> 1zMP -> VM -> EX-P*
*Although the use of VM may negate the need to use MP, but Im not 100% sure?
