I have worked both professionally and personally my entire life in engineering or build and repair. JB weld products are a go to for everything, as long as you choose the correct product for your repair and use it correctly. In this case- we are talking about the steel reinforced full cure time JB weld. (People often jump onto the quik version, but there are drawbacks to that). I n two recent cases I used this on hard plastic surfaces (it does well on metal when done correctly). You must mix it evenly and correctly. your surfaces must be clean. do a dry run fitting with whatever clamping and holding device you are going to use. the JB must be applied evenly and excess removed, and possibly redistributed. If the surfaces match without gaps, do not over apply -otherwise the bond will be weaker, not stronger (the less is more principle here- just a little extra past the thin layer' is ideal). clamp or secure the joint and leave it alone for 24 hours. Seriously that last part. I think people try to test it or play with it too soon. Don't touch it. The items that I repaired recently, really I did not expect even this to work. (the first being on a fitbit 4, the small clip where the body clips to the band is notorious for breaking. This area takes a lot of pulling force and it has held up for weeks on my wrist and getting taken on and off and the band being pulled and so forth- the second is an area on a set of expensive headphones that has a weak spot that again - this holds without issue). There are no other products that compete with the correct JB Weld product. As long as the use matches the product (I have used the high heat, I have used the underwater, I have used the steel stick, and the plastic specific) and that the instructions are followed. I have used this on metal as well, and as a filler, with good results. I know with thousands of reviews mine may seem insignificant, but i want to add to the list on the good side.
