Plugged a small hole in my BBQ smoker and extra large plastic champagne glass

Reviewed in the United States on May 17, 2018

Verified Purchase

I used this to plug a small hole in my Weber Smokey Mountain 22" Bullet Smoker after I removed the factory thermometer and installed a new Tel-Tru thermometer. This product works as advertised and I'm very happy with it thus far. I've only smoked in my smoker twice thus far, but so far, the silicone shows no signs of deterioration and I think it will last for quite some time to come. Make sure you clean your target first before applying this, to give it the best chance of adhering to the intended spot.

UPDATE 8/23/18: So, the other day my wife came to me and said that we had a problem with an over-sized plastic champagne glass that we intended to fill with alcohol for a large birthday party we were throwing (75 people, glass held about 3 gallons of liquid). We had been given the glass as a gift from a friend who worked at a local grocery story. The glass was used as a prop for Christmas/New Years Eve. Anyway, she gave us the glass and we made plans to use it for this birthday party, but unbeknownst to us, it contained a hole near the base of the glass where liquid would fall out if we filled it. My wife discovered the hole while cleaning the glass in preparation of the party, about 8 hours before the start of the party - OH NO! However, when she came and told me about the problem with the glass, I blinked, thought about it for 2 seconds, and said "I Got this! I can fix this!"

So, I dug up the Rutland Products 76C 500-Degree RTV High Heat Silicone Seal, that I had put in my storage shed, and applied a dab of it to the hole. I then pushed it into the hole until it came out the other side. Then I gently wiped the excess from each side and let the glass sit out in the sun for about 5 hours. After that I filled the glass with water and it held the water without a problem! Yay! Problem solved! I then dumped the water out, let it dry until it was party time. When party time arrived, I put some ice and the Holy Water drink I had mixed up the night before (ask me in the comments for the recipe, if you want it, the girls loved it!) into the glass and then the Birthday girls (there were 5 celebrating that night), had he first drink from the glass. The drink in the giant glass was a hit and most importantly, the silicone did it's job and the plug held the entire night. I checked the plug a few days later and it was still in place. I'm very confident that the plug will hold for a long, long time now that it is 100% dry. I definitely recommend this product for plugging small holes, whether they are holes that may get hot, like in my smoker, or they may get wet, like in the example above where I used it to plug a hole in a large, plastic champagne glass.

My handyman used this when installing a new fireplace screen and doors. He said product was easy to use and he really liked heat rating. It is a little thinner than most caulks he has used so was a bit messier. Clean up wasn't a problem, however, and he took the leftovers for his next job.

Perfect for firepit, but be sure you have good ventilation

Reviewed in the United States on June 16, 2016

Verified Purchase

Used this on a recycled granite firepit to assemble the granite slabs and keep them in place.

I wanted a clear adhesive as I didn't want to risk any color staining through the granite and it would hide mistakes better if I used too much or dabbed some around accidentally.

It goes on easy and has a good working time that allows you to re-position your parts if necessary; however, it does give off a very strong odor. I could smell it for at least a day aftewards, even though it's outside in the open (of course, I also used 3.5 tubes of the stuff)! So make sure that you have good ventilation where you are using it.

So far it has held up fine. There is no movement of granite and the structure is very stiff. The heat from the fire does not seem to affect it at all.

Very tough and sticky once dry - mouse proof too

Reviewed in the United States on April 6, 2012

Verified Purchase

We had problems with mice getting through spackle filled holes (just eaten back through) and I needed to seal off the oven to the cabinets. So bought the Rutland Hi-heat silicone.
Worked without problem on the oven, turned a very tough rubber like texture once dry and seals well.
For the mouse topic: seems the acetic smell drove the mouse away until it had hardened. Than we heard it in the wall chewing on it for two days. At which point it gave up and disappeared. Finally!
