BOESHIELD T-9 Rust & Corrosion Protection

Boeshield T-9 gives superior corrosion protection and waterproof lubrication in an easy-to-apply, long-lasting formula. One high-performance formula does it all. Whatever the application, whatever the conditions, you can count on T-9 to work harder, last longer and perform better.

On a seafaring yacht, a dusty ATV or a shower door, T-9 has you covered. T-9 endures muddy bike trails, rain-soaked back roads and salted highways. It withstands farmer’s fields, offshore oil rigs and carpenter’s workshops. For everyone from firefighters and road crews to cyclists and sailors, Boeshield T-9 is the proven solution.

True aerospace technology - T-9 was developed and licensed by global aerospace leader, The Boeing Company, to fill a need for high-performance, long-term metal protection and lubrication. T-9’s unique formulation of solvent carrier and paraffin wax coating was engineered to penetrate crevices deeply, displace moisture, dissolve minor corrosion, and leave a clean, waxy coating with lasting durability - without using Teflon, silicone, fluorocarbons, MEK, or acetone.

Cleans - T-9 attacks existing corrosion, loosens rusty parts and flushes out old lubricants. It is also extremely useful for drying wet parts, electrical motors and circuits, ignitions and connectors.

Easy, fast and clean lubrication - Spray T-9 on and wipe off the excess for immediate use. T-9 dries to a waxy, waterproof finish without leaving a sticky film to attract dirt, dust or mud.

Reaches deeper - T-9 stays liquid long enough to permeate metal crevices and seep deep inside assembled components to leave a durable protective coating that lubricates and protects - all without dismantling your equipment.

One step to long-term protection - Apply T-9 to any metal surface and let it dry. One simple step gives you a thin, penetrating film of durable, waterproof protection and lubrication that endures, month after month, or mile after mile.

Completely waterproof - T-9 dries to a clean, waxy, waterproof film that won’t wash off in rain, puddles or mud. You can rinse away sand, dust and grime with water, while leaving the lubricant intact.

Tough but safe - T-9 will not harm paint, plastic, rubber, fiberglass or vinyl. It can be used on engines, wiring and belts. T-9 is non conductive and will not cause short circuits, so it’s also safe to use on electronics.

Perfect for coastal areas - T-9 is particularly effective for use in protecting all metals in salt water coastal areas.

Easy to remove - Use solvent or any emulsifying cleaner to remove T-9, or simply respray and allow T-9 to dissolve itself before wiping it off.

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.

Style: Rust & Waterproof LubricationVerified Purchase
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.

Great product just a bit expensive! Woman approved too!
Reviewed in the United States on March 23, 2025
Style: Rust & Waterproof LubricationVerified Purchase
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

Developed for use in the aviation industry, the BoeShield keeps the bolts from corroding but what it does for steel wood working tools is why I keep coming back.

Like that mirror finish on your new $2800 table saw ?

Cleane it with a good degreaser and spray on. That’s it. Wipe after 30 minutes and buff just a bit. Wood slides across it better with zero residue being transferred to the wood.

I sprayed every nut and bolt on the golf cart with BoeShiels when I rebuilt the front end. No more frozen bolts and yes, it’s compatible with The popular penetrating rusty bolt spray that have zero lubricating and anti corrosion properties.

Good on bare steel and aluminum topped table saw, band saw, chop saw, drill press, jointer, planer and hand tools!
