VRX is on point with the screw on the ends of some polishing heads so buy wisely. The Mother's Cone is Ok..... But IMO you can buy actual wedges, cones, mini wheels that are the same make up as actual Buff Wheels to get the same results as a stand up buffer would give ya.
Here's a write up I did a long time ago. You can just sub wheels with different shapes. Same principle applies. Oh, if you need to purchase some polishing stuff, run up to a Performance Tool on 59 & Telegraph.
