  2. Paul Hewson

    BrillReally good silicone. Used it to fix a thermistor into my heated bed and to doubly secure the heated mat.

  3. Michael Yelland

    OkayWorks well just takes 24 hours to set really well

  4. Dan

    Good sealant used for alloy thermostat housingProduct itself is good, the tube it’s supplied in not so good, the bottom of the tube split open and it all came out the bottom and made an absolute mess while trying to apply it and believe me it Doesn’t wash off easily. Other than that it is good, I have bought it twice now and this is the first tube that’s split, hopefully just the one faulty one. Either way I’d buy again as it’s much better than other cheaper RTV sealants available.

    Works as describedThis sealant worked just as described, both when installing and after fitment, but only because I followed the instructions implicitly. The cure time wasn’t too long, so I was able to be patient enough to wait before the first start. I found it a little easier to apply than others I’ve used…I applied / installed this around 4 weeks ago now and all still seems spot on. I think if there were to be a problem, I would have noticed long before now.

    Shoe glueUsed to glue sole on bootsI’ve tried shoe goo, and rubber cement with very little success. This stuff however works much better. Been a couple of weeks of hard work in these boots and they still hold together.

    this worked very good in my aquariumtube is hard to squeeze, should have went with a bigger size tube and caulking gun

  11. J in KC

    Easy to use!I used this on my truck window (black rubber seal) what has had fallen and lessened the seal on the window. I affixed the JB weld, clamped for :60 minutes and it’s stayed through rain and 100º temperatures.Pros: ease of use, instant bond, long lasting bond!Cons: none

  12. Ben Winzenburg

    It did the job.Used this to fill in the gaps for an aftermarket grill on my 10th gen Honda Civic Sport (on the top where the retainer clips are). Followed instructions and got superb results; the look with the front grill on it now looks very professional. RTV is not coming off unless I take a scraper or a pick tool and get it off. 👍👍

    Wish it had come with a reamer/cleaner for the screw on applicatorThe idea behind using this adhesive was outdoor wood tiles. See, the tiles are supposed to “snap” together and while you can get them snapped, they don’t stay that way! They slide apart every time you try to move the stupid tiles. I mean I like them and want to use them but if they refuse to stay together, then they are useless. I snapped together two tiles upside down and used this adhesive on the snapped together spots. The box of wood tiles held 36-12X12 inch tiles. What I wanted was a pathway in a dirt part of my yard and having the path 3 feet wide by 12 feet long works for my area. So I will be working up two tiles at a time, snapping and gluing them together until I can make a 3×6 foot section and then another. The slatted wood looks nice and still allowed water to drain down to the soil, yet keeps my feet off the dirt. This adhesive, being waterproof is just what I needed for this project.
