Me too. I'm a little unsure about the sprays. I have a copper color. I also have a 'wet' top coat to give it a more reflective surface.
If you guys want to help, I also thought about a 'dome'. I don't think it would be corny or too much, but a plastic dome to represent the invisible force field. It would act as a dust cover too

It would have to be plastic. Glass would just cost way to much. I've been trying to find something close but its not as easy to find as I thought. It needs to be a dome or a tube dome without a tip or flat or holes. I do want it to look decent, or I won't do it.
It's minimum diameter is 11". So it's big. I've tried garden terrariums, glass dome displays. All too small. I do have a 'food display case' marked. Like the ones you see in grocery stores or a cafeteria to display food.
