I purchased an acrylic isolation box from Amazon. It arrived unassembled and with zero instructions. All the pieces of the box were covered with protective paper. It looks something like this: I've tried heating it with a hair dryer and then immediately cooling it under water, hoping the temperature difference will somehow create air bubbles between the paper cover and the acrylic panes. No luck. The paper covering cannot be peeled off with finger nails. I've read all sorts of suggestions ranging from using peanut butter to nail polish to wd40. Is there some simple solution everyone knows but me?
