stay the hell away from this stuff
after finally getting the parts i need'ed before i could get the truck to the shop the last trip was to the rad shop after taking out the rad and well even after all the flushes and what not they did no good that grainy stop leak chit turned to concrete inside of my rad. caused the over heating and the head gasket to blow you should see the new walls inside of my rad looks like amaze even after a acid bath and a boil no fix
