I have several pairs of rimless reading glasses similar to these:
Some time ago, someone here recommended Loctite 290 (green). I got a bottle the other day, but am unsure how to use it.
The dispenser tip comes sealed, so I used a needle to poke a tiny hole in the tip, but it still comes out in a large droplet that I am afraid will completely drown the tiny bolt and damage the plastic.
I tried dispensing the Loctite with the bottle upright, but was unable to get a tiny droplet to stay on the tip long enough to tough the nut.
Next, I put a couple of drops on a lid and used a toothpick to transfer a tiny amount to the nut. I was able to get the top of the nut to turn green, but I'm not sure I got enough on it to actually penetrate.
Does anyone have any other suggestions? Is a toothpick the right tool? What about a Q-tip?
This has turned out to be more trouble than the glasses are worth. I should just toss them and buy a new pair, but now I'm reluctant to let the glasses win this battle of wills. :-)
