I have used Lisa Pavelka's resin, which I think it Magic-Glos. It was over a year old so it took forever to cure. I left the pieces in the sun and used the UV light on them but, once they finally cured, they looked great.
It was unbelievably messy and sticky though. I assumed that was because it was past its shelf life.
I have. I love Magic Glos and find it easy to use, but for something that big, you'd need several coats to make the resin coat taller than the texture, so you might want to go with one of the old style doming resins if you're doing a lot of them.
I don't have the patience for 2 part resins. i use UV resin. Lisa P's resin is nice if you are using bezels, so there is a "wall" around the outside. I found that MagicGloss tends to pull away from the edges if it there is nothing for it to stick to, like the walls of a bezel. I LOVE UltraDome :) Great stuff !!! They now carry a 2oz sample size so you can test it out. http://www.ultradome.com/supplies.html
Oooh...I'll try it. It's true that MG pulls away from the edges. I wait for it to start, then gently add a little more. It takes me a minute or two, but if I do that, it's fine. If it does pull away, I just add another layer. How quickly does ultradome set?
