permatex RTV never lets me down. this clear silicone is my go-to for sealing up stuff around the shop -- used it on everything from 3d printer enclosure seams to small repairs on equipment. cures up clear so it looks clean, stays flexible after curing, and holds up to heat and moisture no problem. tube size is good for having on hand. only thing is let it cure fully before stressing the joint, takes a day or so to fully set. but once its cured its bomber. wouldnt use anything else for this kind of work

Very tough and durable. Arrived arriving and works better than expected.

I bought this because my supposedly stretch-self-fusing silicone tape wasn't fusing and I needed to glue the tape on/down. My online research suggested that the only thing that will glue silicone is silicone. The tape I was having trouble with was being used on a dishwasher rack repair to cover repairs done with uber goop. Taping over the uber goop repairs isn't necessary but provides some benefits. I first did this a few years ago and it worked real well but now I had some new spots to fix and a few of the old needed reinforcement. I had only a little bit of trouble with the tape the first go around but now half or more of the tape wraps weren't sticking even when redone with a little longer tape. I don't see how but the tape became less good over time. This silicone glue was very hard to use when rewrapping the loosened tape with glue on it for sticking. Covering the job with electrical or masking tape while it was drying didn't seem like it was gripping over the slippery surface (it wasn't). I expected it to fail just about everywhere I did this but to my surprise, it worked every time and the electrical and masking tape later slid right off. I've done at least 10 wash loads since then and all the tape is looking good and no glue is even visible. So this glue is indeed very good for gluing silicone (despite the extreme difficulty of the slipperyness). I notice others have criticized the shoddy caps on these tubes and caps are a pet peeve of mine too. When I have extra epoxy because I mixed too much, I often put some in the hollow tops and sides of shoddy caps which makes them less likely to crack. I also started keeping a small container of vaseline with my glues to use on the threads when closing some tubes to make a good seal - shoe goo definitely needs it. I'm going to add some to my silicone glue tube now and maybe even lower my review for this common manufacturer lack of integrity issue. Update: Prompted by me writing this review and reading a couple others, I took a look at the tube that I got and used a few weeks ago. The cap is indeed of the cheapest quality you will find. I see that I had filled in the top with silicone glue which may make it just a tiny bit stronger, but the sides are wafer thin (the chief problem) and there are only a couple turns of threads. I unscrewed it and could see the silicone would have quickly dried up had I left it like it was. I tried to clean the threads and applied vaseline around the threads and tightened it as much as I dared. Sometimes I reinforce caps with steel (or other) epoxy around the sides which usually makes a difference and I save good old caps. I realize Permatex doesn't make their own caps but Permatex is the one to blame. I knocked a star off my review but even two would have been fair.

Good adhesive for filter gaskets

I used this to glue a silicon strip into a shower window and was worried it won't hold silicone to silicone. It held great!

I really like this stuff. It works on just about everything as long as it is clean and dry. The sealant was very well packed and arrived quickly.

It would be nice if it came with a scrapper to clean the nozzle for future use.
