First I tried using casein with Liquitex clear gesso. I couldn't finish the painting. I'm not sure whether it was the casein or the Liquitex gesso as I'm not fond of either!
I did want to paint so the aluminum background would show so I recently read that Golden's GAC 100 would work as a clear surface treatment. As you can see in the following photo, it's perfect for preserving the look of the aluminum background.
Here is a painting of one of our little hummingbirds in the early morning light waiting for its turn at the nectar feeder.

Art of the Carolinas is coming up again in November and I may just have to get some more of these panels or mail order even sooner! It's so nice when a new support (& new toy) works as well as you'd hoped!
