High quality black silicone at a reasonable price.
Bought this to try to fix a leak on some trim on a truck. Wound up using it for different things such as the soul of a pair of black shoes came loose and seems to work for time and then with reapplication works again. This brand is highly regarded in the industry. I'm sure that I'll get what you said of it. Seems to go a long way.

This is RTV at it's best.
Excellent RTV, and after use, when you put the cap on and put it on the shelf, it will still be good in 6 months. I will never buy Permatex again.

Good product
Great product, but have to use it in a few months. Tried to use some a few months after popping the seal, and the whole tube was solid.

A lot of caulking dry up in the tube
Hard to get out of the tube most of it dry up. I Let set for 3 days because it was cold out when delivered. I got small job done will not buy again. Better go to the store to buy fresh tub.
