Worked fantastic
I used this plastic glue to fix an old Electrolux sweeper cover. The cover became brittle with age and broke when removing. I used this glue to repair the cover. I roughed up the broken part joints with sandpaper for a better bond. it held tight after a day of drying. The cover is stressed during installation and I worried about it breaking again. Nope, it held up. This plastic glue is great and saved my vacuum! Note: The header says black, but the glue I received was tan in color. No big deal for me, but could be misleading if you really wanted black glue.

Fast, strong, sure, Permatex.
Very fast, strong, stable bond. Was much faster at gelling, setting, and becoming useable than JB Weld Plastic Bonder, which had previously failed twice for me. Concerns: Capping the syringe for reuse is more difficult than JB Weld's syringe; air bubbles in the syringe (possibly to low product viscosity) make standing the syringe for a while before opening, and purging important for re-useability; strong solvent vapors require using this outdoors or in a ventilated shop. Strengths: Fast gelling, setting, and develops final strength quickly; easily mixed with provided tray and stirrer, or with whatever you have on hand; due to quick gelling, very easy to work into gaps after mixing until its setting time (fast, no wait); bonds a variety of hard-to-bond-to materials to common materials (plastics to steel); sets hard. Overall, another high-quality Permatex product that they can be happy to put their name on.

Great biy
Does work and is great for quick easy fixes

Very useful for general repair. ...But
A very useful product. Adheres to most plastics and many other surfaces. It will not adhere to Nylon, polyethylene or polypropylene. Reasonably hard in about 10 minutes. Has a beige color. It can withstand near boiling heat and way below zero cold. When fully cured it can be worked with files, drills, etc. It should have a "Use By" date because it hardens in the tube even when brand new and unopened.

Great glue, terrible execution.
Works great. Bonds and adheres superbly. The issue is with the cap. It's terrible. It doesn't stay on or seal out air. I tried taping it on but a week later tried using again and one side was clogged and dried to the point it couldn't be used. Worst product engineering I've seen in a long time. Great adhesive, terrible execution.

Love this stuff but test old/opened Plastic Weld before use.
This stuff works great (as long it is on compatible plastic as some plastics it will just slide off of). I have used Plastic Weld (PW) sometimes with "bondo grate (metal)" suspended in it to make strong repairs. But once you open this glue it seems to degrade very quickly. If you are are trying to reuse a "tube", I suggest make a test blob and see if it hardens (20 min). I just glued some some plastic parts with old opened PW and it did not harden, even worse the "magic" that bonds it to the plastic kept eating and turned the plastic parts into goo!

worked for me
Dries fast and hard. I used it to repair some molding on a honda quad. It seems to hold up to buffalo ny winters. Make sure to rough up the surface your applying it to. That helps it to grip the material to the epoxy.

Pour l'instant, je n'ai pas trouvé de colle plastique aussi remarquablement efficace. Comme son nom l'indique, elle ne colle pas: elle soude. Totalement satisfait.
