I used Klasse All in One on my car. It's quick and easy and gives a nice protective finish that will last. Thinking about trying Blackfire. Has anyone used this? How does it compare to Klasse?

Everyone seems to be into Zaino but it damn if it isn't a hassle.

 

I used Blackfire for over a year then switched to this. It gave me better results.

I think you'll find that it provides higher gloss than Klasse AIO. Some people use both (AIO first to clean and seal, then UPP to add a second layer of sealant).
