Resealed a 72g Bowfront Aquarium
This stuff works Awesome! I resealed a 72g Bowfront Aquarium that had a leak..I filled up the tank after letting the silicone cure for almost a week..Not one drip! If you need to seal an Aquarium this is definitely the stuff to use.

I will take some getting used to working with it but I do like the look
I used this to rebuild an aquarium. I chose SCS 1203 which is black. It seems to be stronger than GE Windows and Doors and might have a slightly longer tooling time, but just an opinion. I will take some getting used to working with it but I do like the look. The only issue is it is a bit more expensive than the GE 1.

Great Psi strength.
Used in a 155 Bow front aquarium. Completely stripped out old silicone and replaced with Scs1200 Psi strength was the highest I could find and need the extra grab for supporting the straps and the Bow seam. I let cure 8 days. Awesome Stuff

Good adhesive.
High quality adhesive product. Very water resistant! This is comparable to The Dow 795 product I've used in the past.
