It was posted here a while back when Kano ran a sale on Kroil. Two cans for the price of one and free shipping at that time.
I ordered two cans and since I'm on their "list" they send me a flyer with the specials ever so often. A six weeks ago I got a flyer advertizing Sili-Kroil, two cans for 18 bucks. I ordered me two.
The first I ordered is AERO Kroil which is STRAIGHT PENETRATING oil. I then ordered two cans of SILI Kroil which is the exact same formula but with and added ingredient(silcone) to also give it some Lubricating properties.
I bought a can of PBBLASTER and used/tried about 2/3 of it but it just don't do the job of the "Kroil". As I mentioned in a post above the plant I worked at did some "trials" on stuff and the conclusion was Kroil was THE best. I know we used it for over 15 years.
Most folks buy PB because they don't know about Kroil or they don't do the work to find it.
GOOD STUFF
