340 shedding piston material

Hello iScamp:
As I remember they were little pellet's (looked like rabbit poop) and came in a quart like oil can and a blister pack thingy...
Simply drop one or two down the spark plug hole and your worriers were gone for a week or two...
Worked wonders when selling a car that needed a ring job.....
Happy Mopar :)

I wish I had a dozen of those cans to display on a shelf.
