This stuff is horrible compared to GE silicone. My 72 gallon tank I am doing right now had a little section left to add silicone to. Very small area. I was out of the GE silicone so went to a hardware store localy. All they sold was DAP silicone. This one tube of it I used will not stop smelling, and it is strong as heck smelling. It smells like vinager. Funny thing is the GE brand didn't smell horrible at all and the smell quickly went away. I have left this tank out all day and last night had the window open in the garage. And this tank still smells strong. I would advise on not using DAP products, I now will not. Anyone with similar experience with DAP?
