Krazy Glue is excellent on plastic. I usually use it to repair my daughter's toys. The other day, I used it to repair the plastic latch on my medicine cabinet that had fallen off. Once this glue dried, the latch held strongly enough to be completely usable once again.Krazy Glue dries quickly and holds tight. I usually hold it in place for 30 seconds and then leave it to cure overnight. Be careful with the hands. I sometimes get it on my skin and it is tough to remove. In fact, I can't remove it by washing. I just have to tough it out until it wears off. A solvent might do the trick, but I haven't tried that.I find the precision tip isn't so precise for me. I tend to get a little too much everywhere. It also clogs every time I use it. I need to use a little needle to unclog the tip before using. The glue, however, is wonderful.Great product. I always have it around for emergencies.
