Best penetration oil

a month ago
Bought Kroil penetrant after multiple others failed. Used Kroil to remove 7 year rusted gooseneck ball hitch from truck bed. Using Kroil, floor jack, and chain after 2-3 hours of soaking and pulling, it broke free. Definitely recommend and will use on all future projects.

Yes, I recommend this product.
