Using aquarium silicone to fix leaky clearos?

I've had the worst luck with clearomizers. Basically the metal threaded cap that's attached to the plastic tank has started leaking to some extent. This is the third one. I generally tend to save crap so I tossed em in a box. So my question is, can I use 100% waterproof silicon and run a circle of it on the outside of the tank where it connects at to stop the leaking?

I don't think I would. While silicon is used to make bakeware and such, aquarium silicon is a different beast. Have you ever used it before? It takes a long time for the fumes to go away, because it odd-gasses when it dries. When repairing an aquarium, it's generally recommended to wait a week or two before filling and adding fish to be sure none of the fumes will leech into your water and hurt the fish. So personally, I wouldn't want to use it.

If you decide to do so anyway, be sure to get 100% pure, high-grade and make sure it's not the kind with chemicals in it to prevent mold and mildew growth.
