Review: High Flex and Oil Resistant Applications - When it comes to working on automotive projects or any high-flex and oil-resistant applications, having the right tools and materials is crucial. As an avid DIY enthusiast and a car lover, I have tried various gasket makers over the years, and none have impressed me as much as the Permatex 82180 Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker. In this comprehensive and entertaining review, I will share my personal experience with this incredible product, highlighting its exceptional performance, helpfulness tips, and why I believe it deserves a resounding 5 out of 5 stars. 1. Exceptional Performance: From the moment I opened the package, I could tell that the Permatex 82180 Ultra Black Gasket Maker meant business. Its consistency was perfect—neither too thick nor too runny—and it spread smoothly, ensuring easy application. I found the 3 oz size to be ideal for most of my projects, providing an ample amount of product without unnecessary wastage. 2. Unmatched Oil Resistance: One of the standout features of the Permatex 82180 is its incredible oil resistance. I have used it on several engine-related applications, including oil pans, valve covers, and even transmission housings. Regardless of the temperature or the type of oil involved, this gasket maker has proven to be a reliable sealant, preventing any leaks or seepage. It's like having a superhero protecting your engine from potential disasters! 3. Sensor Safe and Non-Corrosive: One of the concerns I had when choosing a gasket maker was its compatibility with sensors and other delicate components. Thankfully, the Permatex 82180 is sensor safe and non-corrosive, meaning I didn't have to worry about damaging any electronic parts. This feature gave me peace of mind, knowing that I could use it confidently without any adverse effects on my vehicle's performance or longevity. 4. High Flexibility: In high-flex applications, such as intake manifolds or exhaust systems, the Permatex 82180 Ultra Black Gasket Maker truly shines. Its high flexibility ensures that the seal remains intact even under extreme vibrations and movements. I was pleasantly surprised to find that even after months of usage, the gasket remained intact and showed no signs of cracking or deterioration. It's like a gymnast doing backflips effortlessly! 5. Helpful Tips for Success: To maximize the effectiveness of the Permatex 82180, I would recommend following these helpful tips: • Ensure that the surfaces to be sealed are clean and free from oil or debris. Use a suitable solvent to clean the area thoroughly before applying the gasket maker. • Apply a uniform and continuous bead of silicone around the entire perimeter of the sealing area. Make sure to avoid excessive application as it can lead to excess squeeze-out and wastage. • Allow sufficient curing time as specified in the instructions. I typically leave it overnight to ensure a complete and durable bond. • If you're working on an application where the gasket maker will be exposed to extreme temperatures or harsh chemicals, consider using a primer or accelerator to enhance the bonding performance. Personal Experience: Having used the Permatex 82180 Ultra Black Gasket Maker extensively, I can confidently say that it has exceeded my expectations in every aspect. Its reliable sealing capabilities, exceptional oil resistance, and flexibility make it an indispensable tool for any automotive enthusiast or professional mechanic. I have tackled various projects with this gasket maker, and it has never let me down. Plus, its affordability and ease of use make it accessible to everyone, regardless of their skill level. Conclusion: In conclusion, the Permatex 82180 Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker is a remarkable product that deserves a well-deserved 5 out of 5 stars. Its exceptional performance, unmatched oil resistance, sensor-safe formulation, high flexibility, and helpfulness tips make it a must-have for any automotive project.
