I used those two, side by side, panel by panel on a metallic black BMW 750 after I started hearing rumblings about the similarities. Out in the full sun, neither my customer or I could tell any difference in appearance between the two. Slickness also felt the same after application and 4 weeks later after a couple ONR washes and 1 dealer wash.
I also found this interesting:
Zaino AIO on the left, Duragloss 101 on the right.
Never seen this specific warning printed on anything I have used except Duragloss and Zaino.
Both product lines are also proponents of 100% cotton towels. Does that make them the same, or maybe one is a tweaked version of the other? Maybe, maybe not. If there is a connection, I highly doubt either company would admit to it anyway.
