How long should aquarium silicone take to cure? I read about 24 hours, but I also ran across something that said the vinegar smell ought to dissipate completely once cured. I used some Saturday afternoon and this morning (Wednesaday) it still smells of vinegar. I'm getting impatient as I want to move my project along but I don't want to mess up the silicone, nor have the uncured silicone mess with the setup. HALP!
