Even on cut edges and without sorbitol, there appears to be no signs of delamination or peeling. I'm skeptical... I think it's a trick.. as soon as I coat something important, it will peel!
I'd encourage you to experiment with this wet-media stuff though, so we can say with confidence that it works.
In the meantime, I'm trying to think of some ways that I can stress the coatings to really see how good they're holding. Any ideas?
