I have 3 of the BlackFire products and only been able to use one so I guess it would have to be my favorite so far and that would be BLACKFIRE Wet Diamond Rinseless Wash
I know some black cars that could use this wax I haven't used a lot of BF products, but I have tried a number of different waxes. Out of all them, I would still have to say BFMS wax Blackfire Midnight Sun Batch #25 Carnauba Paste was the easiest to apply and remove. Still my top wax.
I have to say i just love the Crystal seal Create WHIPLASH on paint, plastics, and metal!
I have the 8oz bottle and I dont think i know of an easier product to use. Plus the gloss and pop it gives the car afterwards is fantastic as well.
