Yea... I used a lot of different kinds of metal leaf on here (9um thick sheets), and I used a satin nitro spray finish over it. I didn't have any issues with the nitro and adhesive, but I did notice that for the variegated leaf that had any blue in it the satin finish really ate up the color. Not sure if that was a reaction or just the light. I had to redo that a couple times, and I found that if I used a high gloss finish it was better. Still dulls it a little though.
And yes - she's freaking heavy! 1 3/4" thick....
