The only issue I had with doing exact thing is, one of the small tanks I had kicking around waiting to be a sump had a small leak as well. I filled it and let it sit for a day on saw horses so I could see almost every inch of it. I thought I found the leak, touched up the silicone in the area, let it set & filled it back up. Only to find out that it still leaked. So I decided to start cutting away the old silicone & low & behold the leak was on the otherwise of the tank completely. For the time it takes to peel out the old stuff and put in new, time well spent. Just my 2 pennies & experience.
