I have used all of the 3M products listed above. Here's what my experience has tought me. Perfect It seems slightly more aggressive than Finesse It. I have used it as follows:
First Step: Perfect It
Second Step: Finesse It
Third Step: Scotchguard Liquid Wax
Results have always led the cone-lickers to ask me if our boat is brand new. Creates a great mirror-like swirl-free finish. For steps 1 & 2 I use the 3M foam pad on rotary polisher. For step 3, I apply the wax with an orbital polisher.
