Kroil Original Penetrating Oil (Aerosol Spray-13oz Can-Case of 12) | Penetrant for Rusted Bolts, Metal, Hinges, Chains, Moving Parts | Rust, Corrosion Inhibitor (KS132C)

It does more than get the job done.

This is super expensive but works as it should.

Works like it should in 30 minutes.

Nothing better

Great penetrating oil, but is a little expensive, otherwise I would give it 5 stars

Works well and most importantly smells fantastic.

I sprayed all the bolts on a 1972 C20 Chevy truck front bumper and they all came loose. The smell is not bad at all. I could actually see it go in to the threads on the rusty bolts. Nice to see a product live up to it's intention.

I had used Kroil (formerly AeroKroil) when working on my clunkers, but those days have become bygone days. Now I use this product on firearms. It does a great job on semiautomatic shotguns and pistols and is especially adept at removing rust from metal surfaces.Give it a try, you won't be disappointed.
