Easy spray-on application removes dirt & grime and seals bare metal for long lasting protection. Perfect for all metal products including knives, swords, axes, firearms or any metal part requiring cleaning and corrosion protection!

Easy to use, quality product
Time will tell, but this stuff seems to be quite quality! It was smaller than expected, but you definitely don't need to use much - a little goes a long way and I expect this will last quite some time. Would totally buy again though!

Works really well!
This product cleans steel really well and is easy to use; it also leaves a nice luster and protective layer without feeling greasy.  It even has a pleasant scent!

I'll be ordering some more once my can runs out.

Rust in Peace.
To be honest this is the first time using this product and all I can say is the rust has been blocked and sent retreating back to the evil lands of Rust!

I use all the time
I use this all the time on my swords, axes, and firearms and my wife doesn’t hate the smell of it so I can clean and oil in the house without complaint!

Must have!
There are a lot of rust blockers, but this is a great option.  Grab a can (or two) to help you maintain the classic look of your steel-based products.

Works equally well on my swords and firearms and quite a pleasant aroma too!
- Jon, June 24, 2017 | Verified Purchase
I am disappointed to find that they delete unfavorable reviews, as I have reviewed this product before. I have used this product for years and find it to be less than satisfactory. It's ok if it's all you have but it does not perform as advertised. It does not block rust. I have used it on swords and axes on a regular basis and still have rust issues that require better products.
