Ok, Ill go. I have no experience but just taking a stab in the dark to try to start the conversation.
It seems Menzerna may finish better due to their legendary formula and diminishing abrasives. But due to their body shop focus, I worry about LSP bonding.
It seems Prima Amigo may (guessing) not finish as well as Menzerna but due to its polymers, bonding will be better.
Again, just a theory...
