High Temp Silicone Sealant Professional Grade-High Temp 100% RTV Silicone- Black 10.1 oz

I used it to seal around a wood stoves triple wall flue where it goes through the wall both inside and outside the house. In the past I used the only thing I could find in a hardware store which was fire block calk. That stuff had to be replace each year since it got very brittle and fell off. This High Temp Silicon stuff was much better. Stuck well and stayed pliable even after getting hot. It's been in place since the start of the season and it's now late December.

Sunroof on my car was leaking so the gasket was failing so instead of replacing the unit for 1200$ I 1st tried flexseal,, no luck it cracked and splattered when I sprayed it. I ordered 2 tube of this RTV it covered the entire seal area will 1 tube. L will update after a few weeks or less if it fails,, but as of now I am very happy with the purchase.

Works very well for outside wood boiler rope sealProduct was very easy to use and apply. Let cure for 24 hours and good to go. Only problem I had was not with the product but with Amazon prime. Was delivered a day after there 2 day guaranteed delivery

Seems like a quality product. Used it to glue a refrigerator evaporator tray to the top of the compressor. So far so good.

There wasn't a note about curing time. I applied it in 50° weather and took three days to fully cure.

See photo. Expiration date covered with Sharpie. Why else would a seller cover the expiration date with Sharpie unless the silicone batch is past its expiration date? Delivery was 3 days past the promised date.

The removable nozzle should help with reuse after storage.

Just so everyone is aware. You need a calk gun in order to use this product. This is not stated in the description.
