Hi welcome to Autopia.

step 1: Download DavidB's e-book and read up on paint prep.
step 2: Prep to the max.
step 3: Prep some more.
step 4: Ask yourself if the finish, color hue, reflectivity, gloss and wetness is where you want it to be. If so apply your Zaino.
If not prep some more.
Don't get caught up in seeking (purchasing) a whole bunch of LSP's seeking a cure for a less than perfect prep.
Prep is 95% of the appearance. The trick is as an Autopian is to increase that number to 98+% and only rely on the LSP for a small percentage of appearance augmentation and mostly for protection of all that hard work done during the prep stages.
