Good Enough for Boeing, its Good Enough for Me!
T-9 is nothing short of a magic elixir for anyone who values their cast iron tools, and it has become an indispensable part of my workshop maintenance routine. I rely on it to keep my table saw table, band saw table, and various other cast iron tools in impeccable condition, and it consistently delivers outstanding results. One of the standout features of T-9 is its remarkable ability to protect against rust and corrosion. I've witnessed its formidable protective layer keeping my cast iron surfaces free from the dreaded enemy of metalworking tools—rust. It forms a durable shield that prevents moisture and humidity from causing any harm. What's even more impressive is its versatility. This product not only protects but also lubricates, ensuring that my tools glide effortlessly across their surfaces. It significantly reduces friction, making my work more efficient and accurate. I've found that it's an excellent substitute for traditional wax coatings, offering superior protection and a lasting sheen. The application process is straightforward, and a little goes a long way, so a single can of T-9 lasts for quite a while. This product has truly extended the lifespan of my tools and elevated the quality of my woodworking projects. If you're serious about the care and maintenance of your cast iron tools, T-9 is an absolute must-have. It's a proven performer, offering both protection and lubrication, and it's an essential addition to any workshop. This product has earned its place as the go-to solution for safeguarding and enhancing the performance of cast iron tools, all while conveniently replacing traditional waxes.

Perfect for many jobs, a must have.
Purchased this T-9 for my RV. Was using pure silicone lubricant which is great. The T-9 is perfect lubricant for hinges (even the hinges in the house) locks, or anything that needs lubrication. Not oily and helps to prevent rust. This T-9 is now my go to lubricant. You must give it a try.

High-Quality/Perfect Gift for DIY People
Developed by Boeing Aircraft. I discovered this in 1984 when I had my first boat. Since then I haven't been without it. This is not a WD-40 type product. It’s a high-quality product and has uses that may surprise you, like freeing corroded electrical switches, and it’s a good long-lasting protectant too. The other day I was checking the oil on my car, and it’s been nearly four years since I installed a brand-new battery in that, and had treated the cable connections with Boeshield T-9. The connections still look great and continue to work perfectly. That’s the sort of use that might surprise you. It’s also the longest lasting car door hinge lubricant that I’ve ever found. Friend’s that I’ve given this to, have all had somewhat of a difficult learning curve on what to use it for, at first. I did too when I discovered it. Don’t put it on a shelf and forget about it. Go to the Boeshield T-9 web site as that will give you a basis to work off of in the beginning. It’s been a wonderful product over the years. And no, I don’t work for them or have a financial stake. I consider it special, and one of the best things of the modern world. Just don’t use it wastefully like you would WD-40. Use this on what's important. SHAKE BEFORE USE! I give it a shake every few minutes when using it consistently like on a series of things.

Must have for woodworkers
This is a quality lubricant that provides great value protection for the price. There is no smell at all. I like that it prevents rust my cast iron table top. It also lubricated the top to allow the wood to slide easily. The layers are thick which is good.

Great product just a bit expensive! Woman approved too!
Fabulous stuff as one would hope for the price, which is why it got only 4 stars vs 5. It is very expensive imho. After reading the reviews, I decided to purchase it for some areas on my low mileage, yet aging car. I noticed the doors are beginning to squeak, and when the hood is opened, several areas were beginning to rust. Being a car that is a 2016, but with only 35k miles, I am big into maintenance. (Thanks for the advice, Dad). I sprayed this pretty generously after wiping the areas off. It got rid of the annoying squeaky door, and improved the areas in the inside I was seeing rust on, particularly on the battery etc. From reading reviews, it sounds like this will need to be repeated every 3 months or so. It is similar to WD-40, but has a nice visible protective barrier protecting it from corrosion and outdoor elements. Btw, I am a married woman in my 50's, who found this and did this myself! Very easy & I'll show my other half so he can use it on his even older car as well! Lol
