Great video, looks like a winner.
Some 5 years ago there was an electronic show I was at and a guy was selling demonstrating a super glue, he had a gel and a liquid, he also demonstrated the baking soda method for repairs of plastic parts, he said you can use the soda with either glues but for large gaps use the gel super glue, it was just as impressive, still have my bottle I bought , keep it cold and still is useable.
