Kroil - Brand name of a penetrating oil.

Kano Labs/Maker of Kroil & you would need that to find them on the internet.

Kroil is rarely sold retail. Best price is right from Kano Labs.

They say they are not a retailer but they will bust a gut to get you as a customer.

Kano now has some improved formulas for Kroil. The last one I noticed adds silicone to the mix to add lubricant as the rusted parts start to move.

Their spray cans are expensive but have a nice foamy spray that condences & kinda sucks itself into the part.

I buy it by the gallon & soak cotton balls in it & set the cotton on bolts I want to loosen such as those old fender/grill bolts that rip up the surrounding sheet metal as you try to unstick them & leave the cotton ball set on the bolt for a week.... WORKS GREAT

No I don't work there.. grin I just use it & find it a VALUABLE tool wink
