I had read on this site about the use of Kano Kroil as a rust preventative for storage and how molds treated with a light post use film threw better bullets faster on the next casting session. I am reporting that this is balls-on correct. I have used Kroil on my steel molds for three casting sessions now and can actually say that on this latest session while casting with my RCBS and Lyman 38 caliber molds, they threw perfect bullets on the first, I repeat first, cast.
Prior to using the Kroil, I would need to throw 10 casts before the bullets filled out properly and would have to re-smoke the cavities several times per casting session. Now I don’t.
I don’t know how it does it but the stuff works. This isn’t meant to be a commercial for Kroil but is meant to enlighten other old curmudgeons on here to try something new that actually works.
Has anyone used Kroil on Aluminum or Brass molds with similar results?
