I recently bought this for my new mustang and was wondering if anyone had tried it out or not.

 

I think there's someone around here who uses Blackfire and swears by it. I personally haven't used it yet, but I've seen pics of cars treated with Blackfire. That stuff makes Zaino look like Turtle Wax.

For those who want to know more about Blackfire, here are some links.

I bought the Blackfire kit from this site, and I've got to say it's the nicest polish I have ever used. You get a carnuba like look, with a polish-like durability. No waxy buildup either. My stang is tru-blue (very dark) and the polish is supposed to be best for dark cars. I have no noticible swirls either. I'm picky, and I'd highly recommend these products.
