I was eager to try out my new Blackfire Polish and protectant (QD is in the mail), I wanted to wait for a vehicle that needed a new coat of protectant but ended up working on my fathers dark green lexus whick i klassefied about 4 months ago. It was good though because i have worked on that car before and had somethinig to compare to. The paint is very dark and very smooth so its a joy to work with, but it takes a really good prodsuct to make it look better (klasse improved it a little). I applied both with the PC. I ABC'd first and again, it worked great. I then proceded to work out some etching and belt buckle boo boos w/ FI 2 by hand, and for the first time, i got hazing (probably because i did it by hand and the ab abrasives couldnt break down as much) Then i used the BF polish w/ PC and a white pad. Worked the product in at 3.5 and final buf down at 5 and a quick wipe down with a MF towel. It whent on nicely and spread easier than AIO. The removal was just as easy too. The results were nice, the paint had a nice, even, wetness to it. Just as advertized. Its polishing capabilities are limited (it was able to remove the FI 2 haze though), but it did clean well and my white pad was slightly dirtier by completion. Next i whipped out the BF sealent and used the PC w/ grey pad. Whent on just as easily, but a little tackier. Might be a little harder by hand, but with machine it was a breeze. Let it haze and buffed out w/ MF towel. Would rate the removal as much easier than SG, tiny bit harder than Blitz. When there were small water droplets in the seams and jams, it smeared some, but that wasn't a big problem at all. The sealent deepened the wet shine shine and deepen'd the color slightly. The shine was much better than Klasse and a little better than the Klasse/Blitz that was on there before. Nice and deep yet bright. Looked little more like zaino when layered 4-5 times, so i would say the shine seems better than zaino as well (but never used it so just an observation). Only had time to put anpother layer on the hood and it made a small difference in terms of shine, but it definatelly didnt gum up as with SG. Overall i love this product line and highly recomend it, easy to use, great shine, good price.
