I've read the Zap Gap glue is supposed to be very good, but its pretty expensive for ca glue. Do you think the Zap Gap brand is better than other CA glues? In other words, is it worth buying over something like Gorilla Super glue?
Also, from my past experience with PVC, I remember CA glue working incredibly well on the eye screws. I'm not having any screws pull out by any means, but if I'm making major adjustments to the eye screw when tuning (like if I don' initially have it seated with the eye perfectly vertical) I've noticed that the screw will break free and turn (in resin lures). I make the eye hole so that the eye screw threads in. You can't pull it out, even without glue, but it will pivot if the bond is broken which can throw the lure out of tune.
This is why I was asking about threadlocker red. I've never heard of it being used on plastic. I like using a syringe and needle to inject ca glue, and would prefer to not go the epoxy route.
I have some threadlocker blue, so I'll give that a whorl. And see if it does anything.
