It's expensive because it's unlike any other product and hold patents.

Would they buy this item again? Yes
I was a Zaino user until a friend stopped by with his new black Mustang. I asked him what wax/polish he used because it is hard to get black to look so good and he told me about Blackfire. I used it on my wife's new black CTS coupe and it looks great, easy to apply and remove. Does leave a lot of dust but it wipes off with a fresh towel. No more Zaino, Blackfire is better.
The Blackfire Wet Diamond All Finish Paint Protection gives your paint a new level of protection and an ultra sharp reflection that highlights every square inch of your paint. This formula uses newly developed crystalline polymers, which help reflect light similar to how a diamond does, creating an unbelievably luminous and eye catching shine. It's designed to create the illusion of wet paint, hence the name Wet Diamond and it was formerly known as Blackfire Wet Diamond with Polycharger. Just one application makes the paint look much glossier with a significantly deeper reflection. Don't forget about the long lasting protection as well with the new Polycharger additive. Polycharger is a set of ingredients already mixed in with the Wet Diamond that helps interlock and cross link polymers, instead of having the polymers just rest next to each other. This helps the polymers form an ultra tight bond with your clear coat that gives your paint relentless protection. You can expect your paint to repel moisture, UV rays, industrial fall out, road grime and more for at least 4 to 6+ months. It applies very easily by hand or with a buffer and either method will leave the paint extremely slick and glossy. Few if any products offer such significant protection, sharp reflection and ease of use.
