i just bought blackfire wet diamond a few weeks ago after hearing so many good things about it, and have only used it 3 or 4 times. deffinatley the slickest product ive felt hands down. looks good on light and dark colors. easy on, easy off, and a little goes a very long way. i love it. im just waiting to see how durable it is. tempted to start up another wax/sealant test to include black fire wet diamond, a few others ive gotten since my last test, and the winner of my last test as a control, or something to compare everything else to. perhaps next time its warm enough outside. anyone have any comments on blackfire wet diamonds durability?
