I love this stuff. If it's hard plastic, you can cement it with this stuff. I initially purchased it to fix an aquarium protein skimmer that I broke, which it worked great for. Since then though I've used it for various other plastic bonding needs. I was able to cement a PVC holder to some type of plastic magnet after failing to get a good bond with super glue. I've also done a few other repairs with it. Only issue is, and this is probably my screw up, when it starts coming out, unless you cap the end it will just flow out like crazy. I've made some massive messes with it. Again that is probably my inexperience with this type of cement.
