The paint protection is worthless, it's no more than an synthetic wax coating.
I would wash with Dawn dish soap (only to remove "coating"), you should only use the Dawn if you are waxing other wise use car wash soap.
Hand polish, and the apply Klasse high gloss sealant. This stuff shins and you can layer it. I put a layer on and let it sit over night and the remove apply another and let it sit over night, remove and use a detail spray. Your jeep will look brand new.
