First of all, I think if you are going to list "pad staining" as a negative of HD Speed (even though it has virtually no effect on pad performance) you should have also mentioned that Mckee's 360 also stains pads and is actually more difficult to remove from a pad than HD Speed is. You also could have mention that even though the sealant in Mckee's 360 is arguably the most difficult AIO to fully remove from pads, that is simply a byproduct of 360 having the most durable sealant of any AIO.
The primary benefit of HD Speed vs other AIO's/cleaner waxes is that it CAN be used on nearly any type of trim (even most textured pebble trim) without staining. Also, HD Speed doesn't dust. In most instances where guys are experiencing dusting it's because they are using it like they do w/ other AIO's. With HD Speed, use 3 pea size drops on an unprimed pad. Once the pad becomes saturated, switch out with a new pad for optimal performance. I know it feels unnatural but the product doesn't perform well when used "heavy" like other cleaner waxes prefer.
I tested my sample of blackfire 1-step today on single stage black enamel paint on a 38 Ford and it is seriously impressive. I'm pretty cynical and didn't expect to be impressed by it, and I was worried it would be too oily like Menzerna 3n1 BUT it was a dream to use and very easy to remove even when paired with a microfiber pad. I'm looking forward to trying it on some different paints.
