So I picked up a 120 gallon RR tank. It does not leak but the silicone is in bad shape so I want to reseal. I know I have to remove all silicone to do it right. I have searched and searched and need reassurance. Home Depot has a new GE Advanced silicone that says 100% silicone mold amd mildew resistant. It also say 5x stronger than GE silicone 1. Would this silicone be safe to use. I see no where on tube about mold Inhibitors. Ultimately I know GE 1 is tried amd true but I want black silicone. TYIA
