I'm totally new to it too, I was hoping you were going to educate me to be honest
I had Autoglym protect applied by the dealer to my last car and that's as far as I've gone with it before.
Given how much I'm spending on this car I am tempted to get a proper Gtechniq ceramic coating, which looks to be about £750 after VAT locally.
I asked the question really as you said you weren't that bothered about PPF, so I was wondering why you'd discounted ceramic, which seems to me to be the "I'd like some protection but not crazy money" option!
