I received my BlackFire today - I ordered the New Car Kit (included the Sonus Wheel Gel (thanks!!)) and a bottle of the Quick Detailer spray.
I must say that this product is extremely easy to use and is almost fool proof. I had prepared the car on Sunday, in anticipation of receiving the product on Monday.
Washed with dawn, clayed with claymagic bar (fine), Meguiar's #9 2.0 Swirlremover (to get rid of some light swirls), followed with a touch of P21S Paintwork cleaner, and re-washed with dawn. Covered the car overnight and waited for UPS.
Got the product, read the directions and went to the garage. The polish applies very easily with the Porter Cable and the White CMA pad. I used two pads during the process - the first one caked up after about 3/4 of the car. I should say that I was working the polish 'in' with the buffer, making sure I had good coverage. The residue came off immediately and easily with the help of a MF towel.
Didn't have any of the CMA grey pads, so I used one of my Griots red pads (for waxing). A little BF on the pad and away I went. It's super easy to apply and even easier to buff off. It was cold at my house today - in the low 50's, but the BF still hazed quickly. It buffed off with a MF very easily.
I stepped back and looked at it - it was awesome. Looked just like when I applied Souveran, only I knew this will probably last longer. I decided to apply a second coat since I had extra time (the whole car only took about 1 hour to apply/remove).
I have a grey car (Mercedes E420) and it helped the finish somewhat, maybe more coats will help more. Grey is a hard color to judge...Reflections were crystal clear - I could read the 'danger' sign on my garage door opener motor through the hood, roof and decklid. Not bad!
The BF stuff smells good - the polish has a slightly chemical odor mixed with fruit, the sealer has a fairly strong fruit smell and the spray has a good fruit smell. I also think the spray is easier to use than Z6 - the 'spray thingy' is much 'neater' and sprays nicely.
So far so good. I'll be applying more coats of the sealer after I get back from vacation!
I think if you try it, you'll like it. It's really nice that you can use a buffer with the product and that it's almost idiot proof. I found myself putting too much on at times but it never 'burned' me.
