I dont have time to read all the posts but do not get bummed out over this product streaking, hazing, and being hard to work with. All is easy to overcome.
You must have a low surface temperature regardless of what they tell you. If applying in direct sunlight it will be a mess.
Apply it just like a real ceramic coating, as this is actually as close to a real ceramic as you will get without spending the big bucks. You apply in small sections, then buff with two rags, one in your left hand and one in the right. The left rag will wipe most of it down, then the one on the right will take it to pefection. Any spots that do not buff off, just rub a damp microfiber over it and buff again.
Option # 2 is to do the best you can, and put up with the wierd dark / light spots, and after 48 hrs give it a wash with plain water and dry with a drying spray assuming you did not get it dirt and left it in the garage.
Way better than Collinite 845 from a longevity standpoint.
