I think it is important for folks to make sure and understand the difference between PROTECTION and SHINY. With my Opti-Coat 7 year finish (yes, no re-applying for 7 years) I am protected against things like bird poop, insect acids, etc. - and it is super hydrophobic. When cleaned, it is not as shiny as the cars with Permanon, but one quick application of a detail solution (I use Optimum's detail spray), and the shine is ridiculously beautiful, comparable to the Permanon shine. So the point is from what I am reading, it is important for folks to understand their choice. Ceramic Coatings give you long lasting protection, are super hydrophobic, work inside and out, and can shine great when clean, and super great with a quick detail juice application. If you first apply PPF, well... now you have the protection against all sorts of bad, chips and small dings in particular. So it is a matter of what you want... I may try the Permanon for my non-Tesla's as an alternative to claybar/polish/wax every 6 months. However, for my Tesla, very happy I paid for the extra protection and longevity with PPF and 7 year ceramic coating (I think it was 3 coats?) That said, the Permanon shine is very impressive for such a simple application, definitely interested in trying it out.
