I've used this a few times and so far it's held up great on plastic and wood. The last situation was with sunglasses. I put a very small drop on the frame and squeezed them together. Within 10 seconds there was a solid connection. Just be sure to wipe off any excess product as soon as possible. According to the instructions, you only need a small drop per square centimeter. I grew up throwing in as much glue as possible since Elmers put you gallons in each bottle. But now I've learned how to use super glue and apply quite a bit. However, it is indeed a long way! If you haven't used glue in a while, you'll have glue clogging the pipe. Use a toothpick to remove the hardened glue and you're done!
