I used it late fall since the weather wasn't consistently warm enough for me to get on an application of ceramic coating. It did what it says it should (hydrophobic properties) but I didn't notice much for gloss, but my car is white as well. I did notice it did nothing for keeping contaminants from sticking, I constantly had rusty orange spots on the paint from some sort of fallout. I've never had this problem when using ceramics, so I won't be using fast finish anymore, I'll be using ceramic coating as I had been moving forward.
