Temporary resin edging?

Hello, I have never used resin before but am very crafty and ready to take on my first project. My goal is to do a beer bottle cap resin poker table rail (husbands birthday present) So basically its a separate piece that will be dropped into the table. When it does it will sit flush with the playing surface and the hand rest. The playing surface will be approx 1″ thick, I am going to use 1/4″ plywood as the base for the rail, add the bottle caps and resin so that it meets height of the playing surface…so approx 3/4″ of resin.

Now that you know the backstory, my question is I need a temporary edging to hold the resin in. But since I have never used resin, I don’t know how tacky it is. Will it permanently bond with my edging? Will I be able to remove edging. Can I sand down any imperfections along the edge so it can drop in properly (if needed)? What would be the best material for this? Wood? Plastic? I even saw a post where someone used duct tape as an edge…but I wasn’t sure if that would be the best option. I hate to have to pull out a million staples if I used wood or plastic, I’m thinking that in order to create a bond that wont leak I would need a ton! So the tape sounds like a nice easy option, I just don’t know enough about resin to know if that is the ‘best’. If not duct tape maybe a different tape?

Any help is greatly appreciated. Thank you in advance.
