I'm very curious to see how this pans out.
I've been thinking about buying Overcoat 5.0 but the $100 is a hard pill to swallow when I have 3/4 full bottle of 3.1 sitting on my shelf. That said, I did jut buy Bead Hero because if it performs as good as the couple of videos of it show to it'll be money well spent.
If it's on par with Overcoat for 1/3 of the price then I'll be extremely happy. If not, oh well. It'll go down as fun to try out but a bit of a waste of money just like Diamond Pro Tech Quick Body and Polish Angel High Gloss. Quick Body doesn't hurt nearly as much as High Gloss since it was under $20 for Black Friday. Quick Body was nice to apply and I think looked as good or better than High Gloss, but the water behavior was extremely lackluster. I definitely got caught up in the Polish Angel hype with High Gloss though. It's a nice product to use, but the lack of durability and high cost just aren't worth it.
