81158 Black Silicone Adhesive Sealant, 3 oz. Tube, Pack of 1

This is my goto product for installing carbon fiber spoilers, wings or other performance accessories. I add it to the bottom a spoiler in addition to the double face tape. It’s not over kill and will confidently adhere a performance part that may be under stress like a wing or function spoiler. It will fill in any spaces or gaps between parts leaving a perfect custom look. Easy clean up as well. It also works around GPS shark-fin antennas to seal out any water intrusion. Ie BMW shark fins on roof.

I have to give this one a little more credit then it should. I was in a hurry to attach a "back plate" from the front of my 2020 GMC Yukon Denali because I was replacing it with a LED illuminated one which is flat. Problem was the emblem is what holds the "back plate" on, no glue, just 5 clips. The LED emblem has no clips. So I needed something fast, 2 hour delivery. I admit I bought in haste and realized later that this particular "Adhesive" isn't the strongest for the task, well, after all said and done and a full week of curing it was time for the test. Yes, I went through the carwash. Keep in mind the back plate is about an inch or so thick, but what actually touches the grill is the outline of the back plat design for the emblem leaving less then 1/8 of an inch edge at best. It was pain staking to put only just enough all the way around the whole back plate without putting too much on. After the carwash I was extremely nervous when the big rotating front brush came down and scrubbed the front, i was praying the whole time. As soon as i got out of the wash, i jumped out to see if there was either nothing there, or possibly maybe a broken emblem hanging. Well, not only was it in tact, I pulled on it with both hands with just enough force as to not try to break the bond, but see if it still had held on firmly, and it most certainly did.. I seriously have to say this stuff is amazing.

Excellent product worked perfect

that's great sealant. arrived item on time, well package, great value, sticking good, fast dry, easy to apply, ease of removal, make the job done. appreciated, thank you.

2014 tesla model s Sunroof guide arms broke(sheared) off finally. Not sure if this was original but Tesla stopped putting opening sunroofs on its cars at least partly because of this issue. So, I cleared the sunroof drains, closed it up, pulled the fuse and used this great product to make a permanent OEM looking seal around it to prevent water intrusion.

I used this to seal a few spots on the outside of my RV, and it worked great. It was easy to apply, spread nicely, and created a solid seal. The black color also blends in well with the exterior. A useful product to have on hand for RV maintenance and small sealing jobs.

I buy this tube type as a go-to product and won't ever buy the type with the screw-over clear plastic cover. The latter always lets the silicone set up in the nozzle which ruins the tube unless you punch a hole in it and make a huge mess trying to squirt the unset silicone out of the hole. This style cap (simple toothpaste type cap) seems to keep the silicone intact as long as the cap doesn't fail (I've had some caps which break and then the silicone in the neck of the tube sets up just like the other style cap issue). Permatex is good quality silicone and I've never received a bad tube. I use several colors of silicone and this black is a good shiny black when set. Like any good quality silicone, it's durable, waterproof, heat resistant, and sticks to many things well.

I read the comments first before purchasing and they were not lying ! So my weather strip on my car both driver side and passenger door start peeling off. I should have made a video so yall can see that this stuff actually works ! Last night it rained and I applied this product before it rained. And guess what I came out side to look inside my car to see if rain got in there ! And yall no rain made it inside my car ! Not even a single drop ! The tackiness is 10/10 ! Yes it’s heat resistant and a cheap fix for fixing your door seals. Now make sure y’all before when squeezing the product out because it can be a little messy , if you’re not careful. But other than that 10/10 so glad I brought this ! No odor smell to it at all and dries fast.

El pegamento de alta calidad

グリルマーカーを付けるためにグリルに穴あけをして裏側の配線ごと接着、防水シーリングとして使用。一晩放置で完全に固まって3ヶ月経ってもグラ付きは無いです。効果は文句無し。ただチューブ製なので作業しているとやがて手が真っ黒になって洗い落とすのが大変になるので手袋が必須です。

Nice product

It worked really well. Good quality.
