Ultra Grey

Used Ultra Gray gasket maker on a job that was “definitely not that bad” and somehow leaking from everywhere. Slapped this stuff on, bolted it together, and now it’s tighter than my budget after buying tools I didn’t need. It sticks, it seals, and it doesn’t care how confident you were before you realized the gasket was toast. Oil stays in. Coolant stays where it belongs. No drips, no excuses. If you enjoy products that quietly make you look like you know what you’re doing, Ultra Gray is the hero you didn’t know you needed. Five stars.

Great RTV sealant for 2006 Corolla. Used in timing chain area—the split between the timing block and the engine block—when replacing engine gasket to prevent oil leaks. Car runs better than new! Quantity is more than enough for several vehicles. Water and oil resistant. Let it dry and the adhesion will last a lifetime. Thick but liquid for flow.

If you're using this for a one-time application, you may want to opt for a smaller tube. However, if you use RTV a lot, this tube will last you a long time and the price is on-point. I saved quite a bit overall by just buying the bigger tube instead of smaller individual tubes. This is like that Granny's hot sauce- I use this s*** on everything! Very good stuff, you can cap the tube for reuse. Good high-temp RTV that resists oil and stuff. I've used it on applications like metal-to-plastic and the adhesion is great. The ease of use and thickness is also better than the smaller tubes in my opinion, because you can control the flow using any caulk gun of your choice. I recommend using a "finger" from nitrile gloves to cap the tube along with a wood screw or bolt. The only downside is it takes a while to cure compared to other similar RTVs (like "Great Stuff", etc). I used this to seal around a throttle body that had a snapped corner bolt on a bmw m50 motor, this was plastic-on-metal, and this RTV has held up for literally over 5 years so far with no signs of cracking or anything else. That's after hundreds or possibly thousands of heat cycles and exposure to CCV oils, etc. So yeah, It's very good.

This Permatex 82194 works well for sealing in the kitchen appliances at work. i used it to fix a stubborn leak on a pipe and it held up nicely. the tube is small but lasts a good while. it's nice to have extra on hand for quick repairs.

Great product must have for any oil pan project

Used this gasket maker on my E38 BMW and it worked perfectly. It applies easily, seals up well, and does exactly what you want without any drama. No leaks, no issues—just did its job. Sets up nicely and feels solid once cured. Definitely gave me confidence in the repair. Overall, great stuff and I’d use it again without hesitation.

My 2007 Nissan Altima 3.5 SL with 277k on it finally started leaking at the oil pan. The oil pan in these Altima's use a grey RTV from the factory with no gasket and the Nissan manual specifically call it this product as an alternative compared to their Nissan branded stuff. This worked incredibly well and my Altima is happy again with no leaks. Pros: * Tip is precut so I didn't have to mess with getting it right * Easy enough to use and control the flow * I can simply clean and have access to use more product later so there is no waste * Creates excellent seal when used according to directions Cons: * Takes time to cure properly so if you're in a rush this isn't your jam. They recommend 24 hours before putting oil in the system to allow curing.

my friend used it to fix my valve gasket cover and the car has been running fine. it worked !

箱も中身も問題なし

Very good product !!!

used it for a car water pump change it does the job like other RTVs I tried , other reason because it says " it's save for sensors ".

Used to fit thermostat gasket, good deal.

Works better than expected!
