You realise they’re two different things that do two different jobs don’t you? If you got paint protection/leather protection from the dealership, and your earlier post about buying the car indicates you did, then that will be the application of the protektiv which will be done before you pick the car up from the dealership. If they’re not doing the rebadging for you then the
badges will go on after the protektiv. The protektiv gives the paint an extra gloss, makes it hydrophobic and easier to clean off bird shit, bugs, dirt etc. It doesn’t give you any protection against rock chips. I have it on my car and also have the rock chips.
The PPF is a plastic film applied to certain parts of the car which will give limited protection against rock chips. Regardless of the PPF having a ceramic coating in it, you’ll most likely only have it on the front end and bonnet which will mean the rest of the car will need to be ceramic coated or have some sort of protection applied unless you decide just to stick with factory paint.
You can do the protektiv with no PPF, but I wouldn’t advise doing PPF with no protektiv or some other form of paint protection.
Just remember that the PPF will leave a line of it doesn’t cover a full surface, have a look at the factory applied PPF on the lower rear doors to see what I mean.
