Doesn't form rubber
Left a drop on paper to see how long it takes to vulcanize at room temperature. It has been 18 hrs and this stuff (whatever it is) is still greasy and sticks to fingers ! This is not not I wanted. Very bad product. I need the seller intervention to verify what he has given me is genuine from USA OR a rejected item.

Water pump thermostat housing seal.
The Silicon sealant works good, so far there's no coolant leaks from the water pump. I had to add coolant after replacing the water pump to move my car and park it. Then I left the car to sit for 24 hours so the sealant can cure. Good value and good quality worth the money.

Takes time to cure.
Read the instructions before you buy. I want to put it on the water pump as extra security and crank it up straight away. I will do anyway,however I thought it might cool to point it out.
