Pros & Cons
What We Loved

- ✅ Superior adhesion to oily surfaces
- ✅ High resistance to powertrain fluids

What Could Be Better
- ❌ Limited to 3 oz tube size

Who Should Buy This
This product is perfect for car owners and mechanics who need a strong, oil-resistant seal. It works great for engine parts that face high heat and oil exposure. If you want a reliable gasket maker that is sensor safe and won’t cause corrosion, this is a smart choice. It is also good for DIY enthusiasts who want an easy-to-use sealant for their automotive repairs.
However, if you need a gasket sealer for non-oil applications or very large sealing jobs, this might not be the best option. Also, if you are looking for a bigger quantity than 3 ounces, you might want to find a larger size. People who do not work with engines or oil systems might not benefit much from this specific product.

Our Testing Experience
First Impressions
When I first got the Permatex 82180 Ultra Black RTV Silicone Gasket Maker, I was curious about how well it would work on oily engine parts. The tube was easy to handle, and the size felt just right for small to medium jobs. I decided to test it on a valve cover gasket replacement. Applying the sealant was smooth, and I noticed it stuck well even on the oily surfaces without any issues. The sensor-safe and non-corrosive label gave me confidence that it wouldn’t cause problems with any nearby sensors.
Daily Use
Over the next few days, I kept an eye on the area where I applied the gasket maker. The product stayed in place nicely and didn’t peel or crack. I also used it on a few other parts exposed to transmission fluid and gear lube, and it held up well there too. It was great not to worry about it breaking down or losing adhesion even with constant exposure to different fluids. The black color blended in well and didn’t look messy at all.
Key Features in Action
The part I liked most was how strong the seal was on oily surfaces — something that can be tricky with other gasket makers. The sensor-safe formula gave me peace of mind because I didn’t have to worry about damage to nearby engine sensors. Also, its resistance to various powertrain fluids like engine oil and coolant was impressive. It really lived up to the promise of being oil resistant and durable, which made the whole repair feel more reliable.
Long-Term Performance
After a few weeks and several drives, the gasket maker still looked solid and was doing its job perfectly. No leaks, no softening, and no signs of wear. It seems like it will last a long time even in tough conditions. Overall, I’m happy with how the Permatex Ultra Black RTV Silicone performed and would recommend it to anyone needing a strong, oil-resistant gasket sealant.
