That stuff is such an chemical engineering marvel it has been licensed for use in liquid forms that actually soak into the metal, highly magnetized formulas that are so strong the particles bury themselves into the surfaces so strongly it takes a surface grinder or boring machine to remove them.
It took Dr Hogantightschmdt decades to develop so the particles don't stick together and end up as a clump on the bottom of the pan.
Lately it has found its way in pots and pans as a super hard coating that you can use metal utensils on. This is how it works..
At the first turn of the key the pellets are crushed by compression and release the particles, the first few particles cling to and rebuild the valve faces the few that escape down the exhaust prevent it from rusting for 30K miles.
The rest of the particles fly to the cylinder wall and rings by ultra strong neodidlium magnetic attraction and begin rebuilding the cylinder walls (do not use on over bored engines as it will rebuild the cylinders to the original size).
No you have fully rebuilt cylinder and rings, just like brand new. Now to add the magic.
Put the rest of the particles in the oil, they are suspended in a carrier oil.
They mix in with oil and run around the system plating everything in their path, the oil pump gets rebuilt, the crank gets plated and the magnetic attraction is so great the particles will embed into the soft lead bearing surfaces. In 10 minutes the engine is rebuilt and you saved thousands.
New products are synthetic sawdust for diffs and transfer case and self stiffening tar paper for floor repairs.
