And you probably never will, unless the owners reconsider their "direct sales only" policy. There is no authorized resale of Kroil from any other source, except direct, last time I heard from them.
Could be a good fallback product for local drug dealers, in case their usual lines are legalized.(G)

I buy Kroil at my local NAPA in Westbrook Maine. They buy it direct from Kroil but not all NAPA locations have it. Not cheap though... Our local NAPA also sells Amsoil products and I also buy my Amsoil Saber 100:1 Synthetic two stroke oil there too...

I have a broken stainless bolt stuck into my
diesel's block at the bottom of the water
circulating pump. It has 5 bolt holes, so I have
mounted the pump with just 4 of the bolts.
We tried heat and PB blaster to no avail.
The 4 bolts seem to be enough for now.

If the bolt is sticking out any, you may can get it with a pair of vise grips, and I have cut a slot in one, even if slightly recessed with a dremel and used a screwdriver.
If that fails, either live with four or remove the whole thing and drill out the bolt, often drilling a hole thru the depth of the bolt relieves the pressure and you can get it out
