I do notice a difference between RMG and VM by themselves and when both are used. IIRC, Richt also likes using both. With those products you can build a combo strikingly similar to my own

It's very deep and wet. If that's what your going for, I recommend it highly.
for a QD spray, I prefer clearkote's quikshine. Cleans well and enhances the slickness of the paint noticably.
For clay, the 10 dollar clay magic kit from an autoparts store is fine.
