PC & 3M Pad Recommendation

[BibTyre]

I am going to do some work on my 1963 Corvette which has PPG Concept(Single Stage) paint. I was going to use some 3M 39003 Machine Polish followed by 3M 39009 SMR and topped with Zaino. What pad would you guys recommend for the machine polishe and the SMR? I have the LC Yellow, LC White, and Autopia orange? There are some slight toweling marks in the paint that didn`t come out with an initial application of the SMR and LC white pad.

If you`re not sure then by default start off with a milder combination. It really depends on how much damage you have to fix, so try it on a section and see how that works first.
