GE Advanced Silicone Window & Door Sealant

It is a 30-minute rain-ready and weatherproof caulk, which also provides mold-free product protection for windows, doors, attics and basements. Once cured, Silicone II Window and Door is sun- and freeze-proof, so it will not shrink, crack, break down or wash away even when exposed to harsh weather such as extreme heat or freezing temperatures.
