Corrosion Free Spray

[LX89]

I am wondering if this Corrosion Free in a spray can could be used as a fast acting penetrant on rusty nuts and bolts found on cars.
My supplies of Krown Penetrant and BP Baster are starting to run low, so I was wondering if it would be a good substitute?
Anyone use it or what other product do you use?
DISCLAIMER - This stuff would not be used on any Ford Products, since they don't rust.
Thanks.

I've had good luck with WD40 Rust Release.
It's capable of creeping upwards.
