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.
Review: A really good deal!!! Long-lasting if you cap the tube after use. - 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.

## Questions & Answers

**Q: Hello. Does this  sealer is suitable for my scooter oil krancase  gasket( to sealed it) ?**
A: The Ultra Gray is the BMW Motorrad replacement gasket material for case applications. If it's recommended for BMW motorcycles it's probably great for a scooter.

**Q: Can ultimate grey be used to hang a rear view mirror to the windshield. Mine falls off every few months.**
A: I used high temp double sided epoxy tape. Wash the windshield and the mating surface on the mirror with detergent and rinse. Do not get any finger oil where you will be adhering. using 600 grit sandpaper, lightly abrade an area of the windshield that will be hidden by the mirror trim. Do the same for the mating surface.
Apply the tape (or this adhesive) per manufacturer's instructions. Do it late in the day or in a garage so it's not in a baking car. Give it a chance to cure. If possible, bend a coathanger or something to give the mirror support while it's curing.

**Q: can this be used on water pump Bolt threads?**
A: You bet. Just follow the instructions on the tube precisely.

**Q: Will it help on a valve cover gaskets?**
A: Yes, just make sure you have a uniform thickness on the contact surface. I will usually only put it on the valve cover and not on the head.

### ⭐⭐⭐⭐⭐ Oil pan leak sealed
*by T***S on August 3, 2025*

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.
