I just ironed a book! And it worked! I had a book in my lab whose thin layer of plastic covering the cover was delaminating, and while I have never repaired anything like this before or read anything telling how to fix this kind of problem, I took a wild guess that the plastic was probably originally adheared using heat, so I took my tacking iron to the book! First I put down a barrior layer of silicone release paper, to that I wouldn't get melted plastic on my iron, and then I went at it. I couldn't believe how quickly and how well it worked! Yay for experimentation!
