Always read the lable of any product. The LocTite I have clearly states, "May not be compatible with some plastics".
Just so you won't feel like I'm preaching; a few years ago I sprayed a little WD-40, just a tiny squirt, into the mechanism of my wife's camera because the shutter was sticking open. Yep, now the shutter is open permanently. The WD attacked the plastic parts and seized them. I bought her a new camera.
