I might have to give this stuff a try!!
For me it made solid colors (no flake) like red, black, even white, look spectacular. I'm not dunning it at all.
I did half of my hood (Redondo Red Pearl Honda) with DG #105 and half with 2.0. The next day in the sun both halves looked marvelous but the flake was notably brighter on the side done with #105. The "shade" of the paint was lighter than the side done with 2.0 if that makes sense. I used DG #501 on the hood twice as a cleaner then went back with #105. The flake was restored and equal on both sides and the color itself was lighter as it was prior to the 2.0.
Hardly scientific, just my observations. I would hazard a guess that 99% of folks that use off the shelf products would never notice what I observed.
Next I used it on a sand colored RAV4 that did have flake, same 1/2 & 1/2 hood application. In the sun.....no difference whatsoever that my old eyes could see so I completed the hood with 2.0. Great look & reflections. Durability is an unknown as of now.
FWIW both hoods had previously received three coats of Opti Seal a week or so prior. Both got a wipe down with Poorboy's S&W prior to my informal test.
So, for yours truly, I will use it on light colored flake or solid colors but not on dark colored flake in the future. I'm anxious to use it on a silver/light gray flake but that opportunity has not presented itself yet. I consider it a good/very good product when used on the right color. Good value but not an exceptional product for all colors. I do consider DG #105 an exceptional product which is what led me to the A&B comparison.
I'm not disputing what Luxury detail had to say, just adding my 2 cents worth.
Just one old dude's thoughts........
