Marty, from what I've seen with this stuff I doubt you'd have any peeling problems at edges unless you didn't prep it right and there was contamination. Keep in mind that I have an edge all along my 18 foot door. It looks great everywhere.
I did encounter some bubbling of the clearcoat that I didn't catch in time. They say it's from the concrete gassing. If I had it to do again I would put baking soda water on the concrete to stop the acid activity. The base bubbled just a little but I got all of the bubbles down with a blower, as they tell you to do. The clear didn't bubble at all after we applied it and I didn't expect it to because the base was already cured. However, a couple of hours after we put it down I was in the other shop and noticed the bubbles....it was too late to do anything about them because I couldn't walk on the epoxy anymore as it was too cured to use the spiked shoes anymore. So I let it cure and sanded them down and polished the epoxy.
