Kroil is an excellent penetrant, and worth the extra cost in difficult situations. I know it's a bit pricey but you get your money's worth.

Kroil works itself into that bolt desolving rust and corrosion out of there. It's the only thing i ever use for rusty hardware.

Kroil is the finest. Penetrating oil i have used over my 62 yrs. The finest penetrating oil on the market.
