25228 The Right Stuff 90 Minute Black Gasket Maker, 3 oz, 1 Count (Pack of 1)

I am amazed by the Permatex 25228 Ultra Grey RTV Silicone Gasket Maker for my automotive repair projects. It consistently provides a durable seal that can handle high pressure with ease, perfect for demanding applications. The quick curing time and user-friendly application have truly streamlined my repair work. I love that it is sensor-safe and non-corrosive, ensuring the protection of delicate engine components. With its convenient 13 oz tube size, I can tackle multiple projects effortlessly, and the long-lasting performance is truly impressive. No more worrying about leaks or misaligned gaskets - this product secures everything in place effectively. I cannot recommend this reliable sealant enough for anyone seeking a top-notch solution.

This is a great product. Quick to cure and gets your car back in use, great longevity and does leak. Not juts a clever name.

Used to seal a plain old stamped steel lower oil pan to the aluminum upper oil pan. Followed directions, zero leaks, cures just as fast as directions state: finger tighten, then 60 minutes wait, then torque to spec, then 30 minutes wait, then pour oil in. About the only bad part (and it isn't their fault) is how annoying it is to squeeze it out with a continuous pressure because it's a tube, companies sell "tube dispensing pliers", I just don't do enough of these to justify buying one. Some may wonder just how well it adheres and how easy it is to remove after a fresh application. I had to remove the pan roughly four weeks after resealing with Right Stuff (reason for removal had nothing to do with Right Stuff), so I was able to test the adhesion as well. The old RTV that was on the pan for fourteen years was so weak and already seeping oil past it, that just inserting a putty knife by hand and twisting at one corner removed the entire pan. Right Stuff adhered so well that I had to insert the putty knife into three corners, by hammer, twist just to even start splitting, then do a lot of downward pulling. No damage (or bending) occurred to the pan and it does come off but the adhesion is extremely tight. With the pan bolts on I can see why this wouldn't leak oil and it's been months now with zero drops of oil. Getting the remnants off the lower and upper oil pan was mildly annoying since it was stuck on well, but nothing plastic razor blades couldn't fix. On the second time around re-sealing the pan, I used the same tube of Right Stuff, the pan is 14x9 inches so the tube had enough to do that pan about three times with a ~4mm bead, if you like to smear it rather than bead it, you can probably get more out of it if you smear it without waste. After four weeks the Right Stuff in the tube was just as pliable as when I first bought it, I've never had to re-seal back to back like this with a four week gap between, usually the gap between when I use a tube is months to years and it's dried up by that point, so just know it's going to last a while. Save the plastic nozzle when you're done with it, if you throw the nozzle away you're going to need to buy the nozzle four pack that Permatex sells if you need it again anyway. The nozzle may look like a lost cause because of the RTV in it, but just let it dry and cure, once it dries and cures, it becomes a plug that when pushed (with a pick, ballpoint pen, etc), comes out completely leaving no residue or mess in the nozzle, doesn't adhere to it at all. Also don't attempt to clean the RTV out of the nozzle while it's still wet, you're either going to need solvents which will damage the plastic, or you're just going to spread the RTV thin on the walls of the nozzle and when it dries you're going to have to scrape the inside up to flake it off. Keep it simple, leave the mass of RTV in there whole so that it all comes out together as one piece/plug.

I’ve been using the Permatex 25228 The Right Stuff for a small auto project, and it works well. It’s handy because it bonds quickly and holds up nicely. I especially like how it stays flexible after drying, which helps in rough engine conditions 🚗. It’s reliable when I need a quick seal without waiting forever. Plus, the 3 oz tube is just enough for a couple of repairs, so I don’t feel like I’m wasting product. Overall, I’m glad I tried it out for my car work.
