Review: Works great to clean up a mess - 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.
Review: Excellent RTV Silicone Gasket Maker for High-Torque Applications - The Permatex 82195 Ultra Grey RTV Silicone Gasket Maker is a must-have for anyone working with high-torque and vibration-resistant applications. I've used it on several car repair projects, and it has consistently provided a strong, durable seal that holds up under pressure. The silicone is easy to apply and sets quickly, making the repair process more efficient. It's sensor-safe and non-corrosive, which gives peace of mind when working on sensitive engine parts. The 13 oz tube is a good size for multiple uses, and I appreciate the long-lasting results it delivers. It's reliable in preventing leaks and ensuring that gaskets stay in place. I will definitely buy it again for future repairs.

### ⭐⭐⭐⭐⭐ A really good deal!!! Long-lasting if you cap the tube after use.
*by D***G on March 2, 2025*

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.
