Thanks for this informative and timely post! I was looking for something good to use on my new beast. Just treated the front end Xpel after required wait time using their Paint Protection Sealant.
I went with Griot's garage 3-1 ceramic wax, about $20 -$22 at local Auto Zone for the rest of the truck.
Took it to the park, in the shade. GG 3-1 went on very easy, smelled good, felt 'right' as it was being applied if that makes any sense.
Got to know every nook and cranny of Pearl today. She's happy.
Still have plenty of PP sealant from Xpel, but good know the GG 3-1 will work on PPF per their label/instructions.
Thanks again Jason605, happy camper here.
