Fair enough. It doesn't work for me so I'm done with it. My molds cast very nice without Kroil so I don't have any molds that Kroil would fix to start with. Putting a drop on a q-tip and wiping the cavities of a mold that is very hot and casting fine only to have it start throwing wrinkled boolits for the next 10 or 15 casts (that's about where I quit) is not my idea of "IT WORKS". Kroil does work very well for what it was made for. Anyway Kroil away if it works for you. It does not work for me. It does clean out easy enough though. A shot of brake kleen (that cool things a bit ) and a quick wipe with a dry q-tip and it's back to throwing good boolits.
