Thought I would post my thoughts on the stuff.
I received my gallon Friday and used it on two cars this weekend (Dark Blue Truck and my Black Integra).
My previous detailer was Meguiars Last Touch so I'll compare to it.
Anti-Static:
FK1 425 didn't really do much for the dust accumulation, though we are in the height of pollen season here. There was probably a little less dust than normal but after an hour or two in the garage, there was still pollen all over the car. Maybe a hair less than Last Touch, but not much difference to my eyes. Same went for the truck I did this weekend which I was told was covered in pollen a couple hours after dropping it off. I'm sure the stuff isn't suppossed to be a miracle worker during strong pollen season so I'll re-assess this part when the pollen passes.
Slickness:
Very, very slick stuff. Last weekend I did M21 and AW 12 hours later which is a crazy slick combo. After my wash I wiped a panel down with 425 and it was noticably slicker than the non QD'd side. Compare this to LT which improved gloss some but did little for slickness. From a back of the hand/fingers test it's probably close to twice as slick as the non-QD'd section.
Gloss:
Very impressive. I wiped down the fender and a little got on part of the door. Sprayed and wiped off and there was a BIG noticable difference in gloss between the section I did and where I hadn't done yet. The portion that got on the door showed as that part had much more gloss than the rest of the door. Overall gloss was really nice and seemed to help improve and work with the looks of my LSP combo rather than overpower it. Compared to Last Touch which helped with gloss a little, but not a noticable side-by-side difference while applying the QD.
Ease of Use:
Pretty easy with little to none streaking. I'd spray a section, wipe with MF, flip MF and wipe one light final pass. Using this method it went on streak free even when the MF started to get a little wet from the QD. Last Touch had a little bit more streaking issue, but was also fairly easy to use. 425 is a little better in this area in my opinion. Regarding this section, Turtle Wax Platinum Ultra Gloss QD is the easiest stuff I've ever applied. You don't even have to flip the MF after wiping it off and gloss isn't bad either. (just thought I'd throw that one in there).
Overall:
I purchased this stuff over another gallon of Last Touch for the sole reason of the anti-static properties. Those anti-static properties left me pretty dissapointed. That said, I'm very happy I went with 425 instead of the Last Touch again. Gloss is much better, slickness is like none other, and ease of use equal or better than Last Touch. Anti Static is not worse and a little better than Last Touch but even with that part failing my high expectations, the other features wowed me more than expected. Oh and price.....425 is only like $5/gallon more than Last Touch. I got my gallon directly from FK1's website and it was 27 plus 5 buck shipping.
