HIgh grade silicon for polycarbonate roof panel sealing works as expected
Sealed up a roofing project using Suntuf polycarbonate corrugated panels over a pool pump enclosure. Sticks to polycarbonate plastics. Keep the rain out. Expensive and I only used 5 of the 8 I purchased but easy enough to return to amazon for credit (less small shipping charge). Great that Amazon carries this (for now) as local retailers do not carry much selection of specialized products. such as this.

No good, hard as a rock when delivered. Can't begin to use it.
Old, hard, can't use it.
