Hi George,
I would be glad to help you anyway that I can, that's the great thing about this forum.
Yes the textured light panel is cut into your desired shape, then I painted it a leaf green and a dark green to get some lighter and darker area's. Which makes it look a bit deeper in certain area's. I would use a couple of test pieces first, and when you're happy with the color then I would paint the piece you're going to install. The best way to get rid of the air bubbles when you pour the resin is with a burnsamatic torch. I have years of experience using this torch, if you don't then you must use extreme caution. don't put the flame to close to the resin, and you must keep the torch moving back and fourth across the resin until all the air bubbles are gone. I would stay about 8 to 10 inches away from the resin.
Thanks,
Alex
