Wow, that's some great insight right there, thank you for clearing that up for me.
This past December (shortly after I purchased my Z), I clayed the car, then followed your ZPC video tutorial to a "T", and knocked out 95% of my clearcoat blemishes, which was plenty for me! I followed it up with the rest of the Zaino system and achieved amazing results. Here's a pic (bad lighting but you get the idea)...
Now that you've put that in perspective for me, it makes complete sense how the more coats you add, the shinier and deeper the finish gets. You're basically adding layers of Zaino "clearcoat" to the car!
I will pass your write-up along to my dad and talk it over with him. Like yourself, we enjoy driving our Z's more than cleaning 'em! Thanks again for the info!
